M. G. Leonard has made up stories since she was a little girl, but back then adults called them lies or tall tales and she didn't write them down. As a grown up, she has written stories about fantastical beetles, beautiful birds and thrilling train rides. Her books have been translated into over forty languages and won many awards. She is the vice president of the insect charity Buglife, and a founding author of Authors4Oceans.
She lives in England, by the sea, with her husband, two sons, a dog called Nell, and a variety of exotic beetles. She is the bestselling writer of children's books such as The Ice Children, Beetle Boy, the Adventures on Trains series and The Twitchers books.
Sam Sedgman is a bestselling author and presenter. Before writing stories for children, he worked as a playwright, journalist, and digital producer, and founded a company making murder mystery treasure hunts for adventurous Londoners.
Written with his friend, M. G. Leonard, The Highland Falcon Thief was Sam's first book for young readers. A lifelong fan of puzzles, games, and detective fiction, he grew up with a railway at the bottom of his garden and has been mad about trains ever since. He lives in London.
