Trick or treat, which will it be? A monstrously sweet lift-the-flap book from the acclaimed creator of Gustavo, the Shy Ghost.

Its Halloween night, and Shelley cant wait to play trick or treat! Whats behind this first door? Its a trick! Gustavo and his creepy-crawlies! How about the next door? Its a treat! Mandy with her beautiful jack-o-lanterns! Little readers will gleefully knock on each door, lifting the flaps to discover tricks (such as Vlad in a spider costume) or treats (like Leilas yummy cakes). With a fun interactive element and bright, cheery illustrations, Flavia Z. Drago weaves in cameos by characters from her other books to make this a Halloween treat for old fans and new friends.
