The memorable Casson family is back once again. Eldest sibling Caddy is getting married, but to a young man named Alex, not family favorite Michael. Teenage Saffy feels she has let down her best friend, Sarah, and can’t face her—or her failure. Determined to shake things up, Indigo has taken over organization of the school Valentine’s Day dance. His well-intentioned, misguided plans include matchmaking, so that everyone who wants to go has a scientifically selected date. And Rose, the youngest, who has concerns of her own (not the least of which are ghosts and white vans), observes it all with her usual blend of naiveté and astute understanding. Throw in missing hamsters, Oscar the Mad Art Student, and parents who are off in their own worlds and it’s all . . . well . . . typical, at least for the Casson siblings. Hilary McKay’s story, set in England, is funny, insightful, warm-hearted, and, above all, a delight. (Ages 10–14)
