From Publishers Weekly
In the first of a trio of monster mash titles, You Monsters Are in Charge by Jill Sardegna, illus. by Kees Moerbeek, Mother Monster leaves her baby in the care of 10 well-meaning monsters, who try to abate a baby's tears by playing the xylophone, telling knock-knock jokes and more. The paper engineering grows impressive: first one, then two, on up to 10 colorful, mixed-media monsters pop out from behind a neon-bright band of text against a midnight-black background. Ages 3-6.
