My first children's novel, THE 13 TREASURES, won the Waterstone's Children's Book Prize. THE OTHER ALICE won the Calderdale Book of the Year Award. A PINCH OF MAGIC won a Dutch Bronze Pen Award. My books have been translated and sold in 25 territories worldwide.

Before becoming a full-time writer I worked in publishing as an editor, and before that, as a bookseller. Prior to that, I worked in bars, a bakery, and a second-hand record shop to make ends meet while trying to get my first book deal. I live in Essex and have a son, Jack, and two cats, Widdershins and Lucky.

My next children's novel is A CLOCK STRIKES MURDER, a sequel to TWICE UPON A TIME, publishing in March 2026 in the UK. My debut novel for adults is TWO LITTLE LIARS, a thriller partially set in the 1990s. It publishes in June 2026.
