How old are MG protagonists? An evolving cheat sheet
1024 683 Siobhan O'Brien Holmes

One of the most common mistakes I see in clients’ manuscripts is a main character who is too young or old for the intended audience – middle-aged protagonists in YA, preschoolers in middle grade – and it’s one of the questions I’m asked the most when I give talks to writing groups: ‘How old is too old?’ ‘How young is too young?’ I’ve talked a lot on the blog about publishing conventions and reader expectations associated with middle grade and…

1024 683 Siobhan O'Brien Holmes

Last year I published the blog post ‘Want to read more middle grade horror? Start here! 2021 edition‘ full of recommended kids’ titles in the genre and suggestions for where to find more. But what about all those amazing YA titles? Well, here they are! So if you’re an author thinking about stepping into the YA horror space and you want to get a feel for the market, here are a few excellent novels that received lots of industry buzz…

February wrap-up: A month in the life of a kidlit editor
1024 683 Siobhan O'Brien Holmes

It’s been so nice to get back into the swing of things this month and it feels like business might be slowly starting to return to some sort of normal after a strange 2021. I’ve had a pretty constant influx of enquires and manuscripts and next month is looking super busy with editing, coaching and speaking engagements. I finished my year-long fiction writing programme with Golden Egg Academy in December and it’s been nice getting my evenings back but now the terrifying query process starts with my middle grade contemporary novel. See, authors, I really do know what you’re going through!

Read like a writer: Last One to Die by Cynthia Murphy
1024 683 Siobhan O'Brien Holmes

This was a really fun, pacey YA horror with grown-up Point Horror vibes as Kathryn Foxfield pointed out in her quote on the back of the book. What I found particularly interesting about Last One to Die is that it reads as a realistic slasher up right until the last couple of chapters and then – SPOILER ALERT! – it turns a corner into supernatural horror for the big reveal. I say spoiler alert but actually Kat Ellis’ quote on the back, ‘a supernatural horror-fest’, sort of gives away that twist. This is what sets it apart from Point Horror stories, for me, as those are always based in reality.

Read like a writer using Evernote, part one: Saving examples of clever writing techniques
1024 683 Siobhan O'Brien Holmes

I know it’s easy for me to sit here shouting ‘Read analytically! Take notes! Annotate!’ but that’s not very helpful without practical, actionable advice to go along with it. How do you annotate? What’s the best way to record what you’re reading? So, friends, I’m going to take you through my Evernote system. Lucky you! Of course I’m absolutely not suggesting you have to take notes like this when you read or that you should keep digital records rather than…

Discovering middle grade and YA books in the library (when you don’t know what you’re looking for)
1024 683 Siobhan O'Brien Holmes

If you’ve realised you need to step up your reading game, the library is a brilliant first port of call. I’m a MASSIVE library fan and I go at least once a week. We’re lucky enough to have three lovely libraries in walking distance from our house so I try to cycle through them to keep my son interested, although luckily it doesn’t take much because I’ve put a lot of energy into making sure he loves going (and have…

GMC: The one question to ask every novel you read
1024 576 Siobhan O'Brien Holmes

What if you don’t have the time or inclination to pull apart every book you read in this much detail and just want to enjoy the story? That’s completely fine – it’s important to read for pleasure and sometimes you need to turn off your craft radar and let yourself sink in to the story and experience it as a reader.

Read like a writer: Rules for Vanishing by Kate Alice Marshall
1024 683 Siobhan O'Brien Holmes

I really enjoyed Rules for Vanishing and it reminded me how much I love epistolary novels! Including additional content like newspaper clippings, video footage and police interviews can work really well in books for young readers: it breaks up the main narrative and increases the white space, meaning the story feels a little less dense and intimidating, plus it encourages readers to speed through the pages more quickly because each section is so short and easy to digest.

Here are some lovely things my gorgeous clients have said about me. When I'm having a bad day, I like to read these and eat Cadbury's Creme Eggs.

‘So thorough and rich with insight’

What a treat! This is exactly what I needed. Your critique seems so thorough and rich with insight. I will be sure to send you questions if I’m unsure about anything you meant but I think you’re so thorough that I will be able to digest almost everything on my own just fine. It was an absolute pleasure to work with you as well!
Chanya Sainvilus | YA sci-fi critique

‘Absolutely delightful!’

Thank you so much! Working with you has been absolutely delightful! I truly appreciate your thoughtfulness.

Jena Ataras | MG fantasy critique

‘I don’t want our editing relationship to end yet’

I have just skimmed through your brilliant editorial critique and will follow your suggestions and recommended reading lists. I think you have been very good at steering me the right way. I don’t want our editing relationship to end yet. I still need you!

Akin Jabar | MG sci-fi critique

‘It’s already helping massively’

I want to say a MASSIVE THANK YOU for all that you’ve done for me and my book baby. It’s already helping massively. I already love all the three big suggestions you made and I’m really happy you thought it’s a book worth working on as that’s exactly what I’m planning to do 🙂

Martina O'Brien | Dev edit

‘A breath of fresh air’

Siobhan has not only been a breath of fresh air, breathing new life into my first ever draft manuscript, but she’s also provided me with the impetus to get it finished. Her comments and feedback led me to make some hard decisions but these have resulted in a much better book. Here’s to the future!

David Rogers | MG sci-fi dev edit

I will seek a developmental edit much earlier next time

Well I have read the report and documents and ARRGHH!! But in a good way. I have to say that your comments, suggestions and advice are excellent and I don’t disagree with much if anything that you suggest. They are really helpful and will truly make this book better. Also the pointers will definitely improve my subsequent stories. I will seek a developmental edit much earlier next time as I think this would have made the whole process a quicker and much more streamlined editing process.

‘The best editing I’ve ever received’

Siobhan is absolutely brilliant! I’m trying not to sound too gushy but her work truly is astonishing — the best editing I have ever received. She is immensely creative, able to help solve a manuscript’s problems and repair its shortcomings. She is efficient and generous, bright and fun — an absolute joy to work with. I have never felt so quickly understood and supported by an editor.

‘One of the best things I’ve ever done for my writing’

Getting The Monster manuscript critique was one of the best things I’ve ever done for my writing. I’ve been writing for years, but this manuscript critique has developed and delved into a much stronger, deeper and focused version of my novel. Plus, the book map has offered me a solid, dependable way to create my plots and stories in the future (even if it took me 45 minutes to do one row – eek!). The book map feels unnatural and weird, but I know it’s pushing me to question what I think about every single scene so that I can justify it all. I feel like a much stronger writer and can’t imagine ever working another way – especially now I know my work is always going to benefit from it.

‘Your generous effort has already made the book better’

Thank you SO much for all your notes and for the honesty. I read them all and they’re extremely helpful. I’m very grateful for you taking the time. Your generous effort has already made the book better.

‘The story has been truly seen for the first time’

I just wanted to say thank you so much for all the hard work you have done on my edit. I am absolutely thrilled with it; the attention to detail and depth with which you went into the manuscript left me speechless. The hashtag system is so handy and the book map made so many things clear for me. I feel like the story has been truly seen for the first time. I will recommend your work without hesitation.

Aisling White | YA fantasy dev edit

‘I can’t wait to dive back into my story with greater clarity’

Wow!! This cub report is AMAZING and I need to read it like 16 more times to let it all soak in! You’ve given me such concrete suggestions! I love all of the little tips, suggestions, examples, etc that you’ve provided and I am seriously going to be re-reading this report MANY times. I can’t wait to dive back into my story with greater clarity about the pacing. I also truly appreciate the comps and MG insight! Thank you, thank you!
Jennifer Grolemund | Cub Report (Pacing)

‘I’m really impressed with your critical eye’

Wow, an excellent middle grade manuscript critique! I’m really impressed with your critical eye and what you’ve picked up on here – your comments are very astute and your feedback has been very valuable, as always. I agree with almost everything! Thanks a lot for this – I can’t wait to send you another.
John Lomas-Bullivant | MG fantasy critique

‘I’m so glad I landed on your name in a sea of editors’

I’m seriously so glad I landed on your name in a sea of editors. Thank you for the advice, recommendations, coaching and teaching. It’s all brilliant! I was so clueless and am very grateful to now have this information to guide my thinking. There is a lot of info about writing out there but it’s infinitely better to have someone who can help me focus on the important stuff (with great links) in a contemporary context. I’m very excited about the next draft and think the direction you have proposed in most instances feel right to me. Importantly, I feel empowered by your critique and that makes me more confident that I can produce better work.
Anoshi Mocktar | Critique

Several pennies have actually dropped’

I’ve had a look through everything and wanted to thank you so much for the forensic view of my novel. It’s the first time I’ve had a developmental edit like this completed and it has been, in turn, horrifying, enlightening, surprising and confidence boosting! But I guess you’ve probably seen that before. In many respects, several pennies have actually dropped and I have a firmer idea of what I need to do and will work on more research and reading.
Maria White | MG fantasy dev edit

‘My eyes hungrily soaked up every paragraph’

Thank you so much for the report – I’m going to devour it. My eyes hungrily soaked up every paragraph and I love that you ‘get’ the type of story I’m trying to tell. I will do my absolute best to reinforce your recommendations in the MS. I could rattle on all day but I’m bursting to get back into it.

Valerie Troy | Cub Report

‘I’ve learnt so much from the process’

Once again the insights are amazing. I’ve learnt so much from the process and I think and hope my MS is all the better for your advice and recommendations. It is so beneficial to have an expert opinion on my query package. Honestly, I’ve stared at it for so long that I had run out of ideas but now I have superb guidance to hopefully take the MS and the query package up yet another level. Not a chance I could have done that without your input.

Valerie Troy | Query package

I couldn’t have asked for a better editor

You’ve nailed everything and picked up on the things only an editorial expert can spot! You really have been amazing. I couldn’t have asked for a better editor to help with this! All of your comments have made me realise exactly what needs working on.  They are super informative, and will really lead me in the right direction. It feels so much stronger, and I’m now super excited to see it in print.

‘One of the best editors working with emerging voices’

Like the best of editors, Siobhan will respect your own individual writing style – and work within those parameters to coax you towards ever greater clarity and impact. She has an instinctive grasp of story, and some of the best craft knowledge I’ve ever come across. As a writer herself, she understands the highs and lows of the journey and always has a listening ear. She is never one to rush, and when a script inevitably throws up a knotty issue, will ponder deeply before putting forward possible solutions. Her openness, kind heart and gentleness make her one of the best editors working with emerging voices.

I am completely blown away!

I finally had time to read through the entire Monster critique and I am completely BLOWN AWAY! Your feedback is SO helpful and SO thoughtful. You are a truly talented editor! Not everyone has your gift to provide notes that are so comprehensive, succinct, and meaningful! You’ve given me ideas, direction, and underscored the key elements for crafting MG in the horror genre. This is the best Christmas present I could’ve ever wished for and I need to read it at least a hundred more times to let it all soak in…and to percolate all of the ideas that are already flowing in my head. Thank you from the bottom of my heart. I am so grateful to have this opportunity!

‘I’ve never felt so quickly understood and supported by an editor’

Siobhan is absolutely brilliant! I’m trying not to sound too gushy but her work truly is astonishing — the best editing I have ever received. Siobhan is a master editor at every level, from word to idea. She is a consummate craftsperson and expert researcher. She is also immensely creative, able to help solve a manuscript’s problems and repair its shortcomings. She is efficient and generous, bright and fun — an absolute joy to work with. I have never felt so quickly understood and supported by an editor.

‘I can’t believe how lucky I was to encounter you!’

Thank you so, so much for this. I actually jumped for joy when I read your first comments! I couldn’t respond immediately as I was travelling but this took away so much of the stress of the flight – I was on such a high (literally!) There’s so much to take forward. Thanks so, so much again, Siobhán; I can’t believe how lucky I was to encounter you!

Thank you for your tender loving care with my manuscript and all your kind words, and for providing such detailed, useful feedback.
