From Candlewick Press:
Some of the kids in Marilyn’s class have monsters. Marilyn doesn’t have hers yet, but she can’t just go out and look for one. Your monster has to find you. That’s just the way it works. Marilyn tries to be patient and the kind of girl no monster can resist, but her monster doesn’t come. Could she go out and search for him herself? Even if that’s not the way it works?
“Rich with feeling . . . a warm, gently funny reminder to chase down one’s dreams, rather than waiting for them to appear on the doorstep.” — Publishers Weekly (starred review)
