Though bedroom monsters are a dime a dozen, this one’s a bit different. Looking like a black wombat with a bright-red clown nose, the Creature that lurks under wakeful young Jo-Jo’s bed is but the size of an ant. A hungry one, however, who starts absorbing all the darkness it can find. Going the “Fat Cat” route, the monster proceeds to swell as it sucks the dark not just from the bedroom but from the entire world and beyond—leaving confusion and dismay in its wake, until “There were no shadows and hardly any dreams. There was only the light. The stark and staring light.” Liao, a popular Taiwanese illustrator, creates polished, sometimes wordless cartoon scenes featuring a monster whose only scary characteristic is its eventual humongous size. Ultimately Jo-Jo’s tears draw the behemoth back to Earth, where a cuddle and a “darkness lullaby” puts them both to sleep and allows all the darkness to leach back into the universe. Not exactly entropy in action, but a cozy, if lengthy, bedtime tale nonetheless. (Picture book. 5-7)
