John Dougherty was born in Larne, Northern Ireland, and not many years later they made him go to school - an experience he didn't find entirely enjoyable. Fortunately, the joys of reading helped him through the difficult times. It's therefore not completely surprising that when he grew up he became first a teacher (the nice sort), and then a writer of stories and poetry for children. He also writes songs, some of which he performs with First Draft, a band made up of three children's authors and a bookseller.

He now lives in England with his two children.Thomas Docherty is an author and illustrator of childrens books based in Swansea.

His books have been sold around the world and have eben translated into more than 25 languages.
