Monstra vs. Irving

Everybody thinks Irving's little sister is adorable. Everybody but Irving. To him, Claire is nothing but a little monster. He even calls her "Monstra."
So Irving decides to teach her a lesson. With the help of miraculous Monster-Ade, he'll turn himself into a monster--a real one--just long enough to scare Claire silly.
But his plan doesn't quite work out the way he intended. How do you handle a monster in the family?
Stephen Manes knows how to make kids laugh. They'll howl with delight at this monstrously hilarious book.
