Echo City is a strange and frightening place indeed, and for new arrival, Charles, it seems to be a most unfriendly place. His possessions are disappearing, and there seem to be monsters everywhere. Fortunately for Charles, he gains the friendship of Margo Maloo, who bridges the divide between humans and monsters. For reasons that aren't clear at the start, Margo has managed to tame all these monsters, and they seem more afraid of her than she is of them. Anyone who likes trolls, ogres, and goblins with a couple of ghosts tossed in on the side will find this graphic novel highly entertaining. Although it's filled with humor and Charles is not the most adventurous sort, the book also contains hair-raising situations that will get readers' hearts pumping much faster than usual since it isn't always clear how everything is going to turn out. Late elementary and intermediate readers are the perfect audience for this book.
