Rob Biddulph strikes five-book six-figure deal with Macmillan Children’s Books

Macmillan Children’s Books has acquired five middle-grade titles with bestselling author and illustrator Rob Biddulph in a "major" six-figure deal.

The deal kicks off with the Moonhaven Chronicles, a “thrilling, fast-paced, commercial middle-grade duology” for readers aged eight to 12 that will launch in February 2026 with The Last Wolf. World all-language right were bought by associate publisher Sarah Hughes from Jodie Hodges at United Agents.

The Moonhaven Chronicles follow four friends Jax, Jovi, Esau and Fourth, as they sneak out every full moon, breaking a strict curfew and enjoying the freedom of the deserted streets of the small town of Moonhaven.

One night, news of a rare werewolf attack turns suspicion on the friends and they have no choice but to run. As the mystery unfolds, "rumours start, friendships are tested, secrets are kept and broken and the friends don’t know who to trust – not even each other".

The Last Wolf will launch in hardback with 100 black and white illustrations, and the second title will follow a year later. The launch will be backed by an extensive PR and marketing campaign with school and festival events, creative partnerships, social-media advertising, draw-along-activities and more, the publisher says.

Hughes said: “Rob is one of those rare people who dazzles with both his writing and illustration for children of all ages.”

Biddulph added: “Writing and illustrating for this age group is an utter joy… I’m so proud of The Last Wolf – a story packed with mystery, adventure, cool black cloaks, full moons and, of course, werewolves. I think fans of Peanut Jones will really love this new series.”
