What’s it about?

The story.

In the third Kitty Quest adventure, Woolfrik and Perigold are drawn into a suspicious family reunion when Princess Horribelle appears, but the visit soon becomes much more complicated than it first seems. An old nemesis with a grudge against Kitty Quest returns, turning what might have been awkward family business into another comic fantasy crisis. The book stays true to the series formula: kinetic full-colour panels, animal heroes, frantic danger, silly names and jokes that keep the fantasy peril from feeling too heavy. This volume adds a useful twist of family tension and villainous plotting, making it slightly more suspenseful while still squarely aimed at younger graphic novel readers. It should suit children who like a clear good-versus-evil structure, expressive cartooning and fast stories that feel more exciting than demanding.

Phil Corbett

Phil Corbett is a British author-illustrator best known for the Kitty Quest middle-grade graphic-novel series (Kitty Quest, Sinister Sister, Trial by Tentacle), gleeful fantasy-adventure comics about a pair of underqualified amateur monster-hunters scrambling through magical chaos.
