What The Dickens
by Gregory Maguire
An infant tooth-fairy, orphaned or abandoned, hatches from its egg beside a stream, stretches his tiny limbs, and runs straight into wayward birds, a pet cat named McCavity, a boy, and a tiger. Later, he runs into a girl tooth-fairy and encounters the rest of tooth-fairy society. Meanwhile, out in the world, he's a night-time fantasy told to three home-schooled kids whose parents have been called out on an emergency that might be The Cat In The Hat but might, for all we know, the Judgment Day.
