It's the latest thing. Each one is just right for its boy or girl. Marilyn really wants a monster, too, but despite her efforts to be the kind of girl no monster could resist, hers just doesn't come. What could be taking it so long? Everyone knows you just have to wait for your monster – but the spunky and determined Marilyn thinks there may just be other ways that things can work. Matt Phelan's expressive artwork brings Michelle Knudsen's appealing cast of children and monsters to life, creating a sweet, warm tale of friendship perfect for sharing.
