Seized by an inexplicable impulse, Caitlin does a quick switch at Rigby's Resale Shop: she leaves her longtime favorite doll in place of a pretty doll that's on display with a fabulous wardrobe. The new doll proves to be unusual: when she's alone with Caitlin, she comes to life, demanding the clothes Caitlin left in the shop and explaining that her name is Holiday. Caitlin is entranced, despite Holiday's difficult character: she plays loud music on her tiny radio, cultivates her tan, is furious because Caitlin can't afford to buy her a lot of clothes, and is generally self-centered. Only after Caitlin responds with righteous indignation does Holiday become more reasonable. Caitlin and her friends are believably portrayed as children whose dolls are an important part of their imaginative lives; their interaction, as well as Caitlin's with Holiday, is realistic and pungent with humor. Despite Caitlin's mother's astringent response when she discovers where Holiday came from, Griffith doesn't quite resolve that moral issue, and her conclusion is a little abrupt; still, a lively, easily read dollstory. Nice occasional soft-pencil drawings.
