The details in Wells' illustrations showcase Felix's and Fiona's different personalities brilliantly and cleverly stretch the story out to the endpapers. Concise and kid-appropriate language combines with darling drawings (who can resist cute little guinea pigs?) for another feather in Wells' literary cap.
A worthy addition to memorable picture books about bullying and self-worth, like Helen Lester’s Hooway for Wodney Wat (HMH, 2002) and Anna Dewdney’s Llama, Llama and the Bully Goat (Viking, 2013).

With a cast of guinea pigs who correspond to instantly recognizable human types, this series opener from Max and Ruby creator Wells humorously captures the fluidity of social dynamics—and proves that it’s possible to captain one’s own destiny.
The notion of a shy protagonist standing up for himself in order to fend off a friend’s goofy ideas is an interesting twist on the theme of self-assurance. Fine for reading aloud.
Felix personifies the problems that most children face, and provides a useful conversation starter about bullying and standing up for oneself.
