Bouncier than a bowl of Jell-O, innately bubbly Lucy Rose, eight, undergoes a tremendous struggle; her parents have separated and the resulting upheaval leaves her no comfort zone. Her inherently positive attitude and family’s nurturing care, revealed in Kelly’s deft use of first-person narrative, shows how a sparkling personality copes with serious as well as marginal problems such as obnoxious boys in her new school. Lucy Rose does not always know what her observations of family and friends mean, but between the lines, readers can see what she does not: how her parents are coping with their new arrangement while trying to keep life as normal as possible for their daughter or just how truthful the responses from her advice-columnist grandmother are. Lucy Rose’s mental growth is perceptible; she develops into her new situation, learns to set aside her longing for the past, and builds a new life, all in a text that delivers these mature and complex concepts simply enough for her young audience, an amazing feat for any author, especially in a debut. Overall, the wonder is that third-grade vocabulary is sufficient to communicate the depth of Lucy Rose’s hard-won growth. (Fiction. 8-11)
