A mother ghost soothes her baby to sleep as dawn draws near, summoning visions of ghouls and goblins to help him in his slumber, reassuring him that the “boy / with ten pink toes, blue eyes, / and golden hair” he thinks he sees is “only make-believe.” Lemaitre, working in digitally colored bamboo and ink, presents ghosts of the classic, sheeted variety, big eyes and tiny smiles lending them expression. His colors modulate from a gorgeous purply blue to rosy pink as the day brightens; he depicts the monsters the mother conjures in childlike fashion—there’s nothing at all scary about this book. Although the ghostly role-reversal premise is hardly new, this is a just-sweet-enough example of it for little ones. (Picture book. 3-6)
