Quick Assessment

Prez moves in with a foster family in the country after his grandfather can no longer care for him, then meets Sputnik, a strange boy who is secretly an alien trying to save Earth. The story handles grandparent dementia, the loneliness of changing homes, and a light sense of cosmic peril with plenty of humor and warmth. Parents should expect an emotionally tender, funny adventure where the heaviest material is family loss rather than frightening content.
