Katherine Halligan – Editor

Award-winning author and highly experienced former publisher of illustrated children's books


I am a highly experienced former editorial director of children's books, specializing in picture books, illustrated non-fiction, novelty, and gift. I have held senior roles at various UK publishers, including Macmillan, Scholastic, Simon & Schuster, Nosy Crow and Penguin Random House. As a versatile and dynamic children's book publisher, I have edited, commissioned and published hundreds of successful titles, and I have written over 150 books as an editor. Some of my best-known editorial projects include:

* The Lion, The Unicorn and Me, by Jeannette Winterson and Rosalind MacCurrach (Scholastic UK)
* Eliot Jones, Midnight Superhero, by Anne Cottringer and Alex T. Smith (Scholastic UK)
* My Mum is a Supermum, by Angela McAllister and Alex T. Smith (Scholastic UK)
* You Can't Eat a Princess! by Gillian Rogerson and Sarah McIntyre (Scholastic UK)
* Aliens Love Underpants, by Claire Freedman and Ben Cort (Simon & Schuster UK)
* The Perfect Bear, by Gillian Shields and Gary Blythe (Simon & Schuster UK)
* This Little Baby (Campbell Books UK)
* Poppy Cat, by Lara Jones (Campbell Books UK)
* How To Help a Hedgehog and Protect a Polar Bear, by Jess French and Angela Keoghan (Nosy Crow)
* So You Think You've Got It Bad? A Kid's Life in Ancient Egypt, by Chae Strathie and Marisa Morea (Nosy Crow)

I am also the award-winning author of HerStory (illustrated by Sarah Walsh, published by Nosy Crow UK/ Simon & Schuster US), as well as several other new and forthcoming titles published by Walker Books and Nosy Crow.

I love every part of the creative process, and with many years of experience in making books and leading teams, I am proud of all my books. I believe in creating child-centred books that entertain and delight, whether they are fact or fiction, and that the very best books should make you laugh or cry... or sometimes both! I also believe that creating a book should be a happy experience for all involved, so I bring positivity and fun to all my projects.
