David Solomons’ science fiction adventures are laugh-out-loud funny and have won several book awards. In this latest, Gavin finds himself with the fate of the world in his hands. The new girl at school, Niki, is really getting on his nerves, following him everywhere and declaring that she has never seen anyone so cosmically insignificant. He doesn’t believe her assertion that she is a galactic princess, trying to evade her warring, alien despot parents.

However, a series of surreal events including being taken hostage by a talking bounty hunter cat called Cupcake, soon make him change his mind. To avoid Earth being obliterated, Gavin must help Niki’s crew repair her spaceship as well as try and bring her parents together again.

Family and friendship are at the heart of this story. Gavin is fostered but worried that he is about to be moved on again, ousted by the baby he calls the Tiny Horror. Although Niki may seem to live a privileged life as a princess, her parents are fighting, forcing her to choose between them. Despite her annoying behaviour, Gavin realises he will miss Niki if she leaves whilst she has come to understand that families can grow from other relationships.

Hilarious and ultimately heartwarming, with inventive detail, this will appeal to readers in upper KS2.
