Let’s get your book ready to unleash
on those young readers
Hello and welcome!
I’m so happy you’re here. I can tell you’re going to be one of my favourite people because you’ve slogged through multiple drafts, cried into your gin, wondered whose idea this book was anyway and made it to the other side. Plus you were brave enough to write a story for young people – a demanding audience who deserve the very best. But most importantly, you’re so serious about your writing that you want to hire an editor to get it to the next level.
I think I love you.
And I want you to love your book. To be completely, utterly, hearts-for-eyes smitten about your story. So I’ll help you make your characters unforgettable, your scenes full of drama, your setting vivid and your dialogue snappy. I’ll look at anything that might pull readers out of the story and distract them from the world you’ve built so they can stay captivated right to the last full stop. Let’s get this book ready for young readers.

The Writer and the Wolf mission statement
Young readers deserve the best books. They deserve authors who care about their readers and what’s important to them. They deserve to see themselves reflected in the books they read, and to feel valued and important. They deserve stories that help them see the world in new ways.
And I couldn’t be more excited to lift you up and support you while you create those stories for them.

‘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.

‘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. Siobhan is a master editor at every level, from word to idea. She is a consummate craftsperson and expert researcher.
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.
