About This Book
The sharp scent of fresh-cut grass mixes with the distant hum of worried voices on the radio. Rex, almost eleven, feels the strange buzz of a summer filled with secrets and fears. As new faces appear and old worries fade, he begins to see that even when the world feels uncertain, friendship can light the way.
Themes
Quick Assessment
Rex, ten going on eleven, moves from Vancouver to Ottawa during the Cold War and tries to make sense of adults who seem terrified of nuclear war, while he settles into a noisy household of five siblings and new friendships. The story mixes mystery, funny family scenes, and quiet worries about fear and the future, with only light peril from a rumored creature. It suits confident independent readers, and parents may want to talk with children about the real-world fears of that era.
