Thomas said: "This novel is a summer holiday in a book... It's full of Kate's wise understanding of friendship. It's a great read and an escape, and it's also very wise, particularly on difficult families, first love and perfectionism. Readers are going to love it, and it's such a joy to be working with Kate again."
Mallinder said: "I'm thrilled to continue working with the lovely Firefly team, and for the opportunity to write more adventures for Sasha, Hetal, Cam and Nell."
Firefly will publish in spring/summer 2023.
