Ghigna's (Animal Trunk) somewhat attenuated, workmanlike poetry collection takes aim at grown-ups, siblings and bedtime fears. One costume-seeker laments, "I've searched through stores all over town/ For one old scary ghoul,/ But none have masks that look just like/ Our principal at school." Another child stays up late: "A shadow drifted down the stairs/ Appearing pale and calm,/ But when it shouted, 'Go to bed!'/ I knew it was my mom." McCauley (The Lima Bean Monster) accents his high-contrast black-and-white illustrations with jolts of purple, orange and green, but like the sing-song stanzas—and despite the arresting jacket art—the stylized designs within lack convincing energy. Ages 4-8. (Sept.)
