Rachel Chivers Khoo was born in Belfast. Growing up, her greatest wish was to become a published children's author. Now that wish has come true, she's planning on making more wishes . . . possibly involving a puppy or a lifetime's supply of cinnamon buns. Rachel Chivers Khoo studied English literature at Trinity College, Oxford, and creative writing at Queen's University, Belfast. She previously worked in book publishing and wrote her debut novel, The Wishkeeper's Apprentice, at her kitchen table during maternity leave. She lives in London with her husband, two young sons, and far too many books.

Rachel Sanson is a children's illustrator from the UK. Originally from a little town in the north of England, she studied illustration at the University of Lincoln. Growing up, she wished for superpowers. It hasn't happened yet but hopefully someday soon. Rachel Sanson's hobbies include being nocturnal, making friends with cats, and hiding under large piles of blankets. She lives in Bristol, UK.
