Abie Longstaff is the eldest of six children and grew up in Australia, Hong Kong and France. She knows all about squabbling and bossing younger sisters around so she began her career as a barrister.

She started writing when her children were born. Her books include The Fairytale Hairdresser series and The Magic Potions Shop books. She has a life-long love of fairy tales and mythology and her work is greatly influenced by these themes.

Abie got the idea for the Trapdoor Mysteries from her parents' house in France. The house is big and old, with lots of rooms and outbuildings. In one of the bedrooms, there is a secret entrance hidden in a fireplace. It leads to a room that was used by the French Resistance during the war. It was the perfect idea for a book!

Abie lives with her family by the seaside in Hove.

Eve Coy always loved to draw. She studied animation at Edinburgh University and became an artist working for Aardman Animation. When they lived in Bristol she would take her first daughter to the library which had a fabulous children's section, placed on shelves inside a boat.

She and her daughter were frequent passengers on that boat, and as they worked their way through the shelves Eve became hooked on picture books. Eve gained an MA in Children's illustration from the prestigious Cambridge School of Art and Looking After William is her first picture book.
