Jamie Hammond biography

Jamie Hammond is a British author–illustrator and children’s book designer. He works in trade publishing and has served as an art director in UK children’s fiction, alongside developing his own illustrated stories for middle-grade readers.

Hammond’s debut as author–illustrator, Grumpfort, was published by Usborne in February 2025. Written for roughly ages 8–12, the fast-paced, heavily illustrated novel follows Mo, an inexperienced “Warden” whose monster-hunting duties lead him into a conspiracy surrounding the fortress of Grumpfort. The book combines comic adventure with accessible page design to support developing and confident readers in upper primary and early secondary settings.

Following the success of his debut, Hammond announced a companion adventure, Dragonflare, an illustrated novel set in the same world and positioned for readers eight and up. Professional profiles also note his continuing work in children’s book design, bringing experience of layouts, typography and branding to series development.

Hammond’s public author materials emphasise themes of courage, friendship and inclusivity, and the value of seeing a diverse cast centred in humorous fantasy. He is represented by literary agent Lydia Silver.

Selected works: Grumpfort (Usborne, 2025); Dragonflare (forthcoming).
