With distinctive illustrations, Hanoch Piven crafts a delightful story of competitive siblings whose attempts to frighten each other--revealed through 8 gatefold pages--are surpassed by their baby brother. Mo and Jo are sweet kids who engage in costumed one-upmanship until they’re surprised by a “real” monster who turns out to be the baby, Bo. Piven’s unique approach-showing the photographed objects that will be used in the children’s disguises on the outside of the gatefold, and revealing the finished face when the fold is opened-brings a sense of excitement to this simple but compelling story for children aged 4 to 8.
