Llama Llama Trick or Treat

In his sixth board book, Dewdney’s Llama Llama is in a great mood, and who can blame him, between costume picking (“What would Llama like to be?/ An astronaut? A bumblebee?”), pumpkin carving, and the promise of candy to come. Classmate Nelly Gnu can be spotted in a few of the scenes, including a closing spread of trick-or-treating, whose dark, rich colors really pop after all the white space on the preceding pages. A cheerful outing for kids just starting to enjoy Halloween. Up to age 3. (Aug.)
