First- and third-graders Jake and Abigail alternate as narrators to describe a series of trips: boogie boarding at the beach, riding the Gravitron at an amusement park, visiting the emergency room, losing each other in the mall and canoeing the Everglades. The focus is always on the siblings, although adults—extended family and in one case a babysitter—accompany them. A bonus episode is told by the cat, Fluzzy, whose response to their trips is completely convincing. Each story is simply told with quiet humor, sometimes more a vignette than a rounded narrative—but, as always, Blume gets right to the hearts of her characters, revealing their fears, their resentments and their affection for each other. Stevenson’s grey-washed cartoon illustrations enliven the pages. Each chapter can stand on its own, making this particularly accessible for the struggling reader. This is the third of a projected quartet of chapter books, sure to be welcomed as enthusiastically as its predecessors were. (Fiction. 6-9)
