Hi!

A string of comically stylized animals greet each other in masterfully rhyming couplets-an owl's "hoo" is answered by a cow's "moo"; a crow's "caw" is returned with a donkey's "hee-haw"-all leading up to the "hi!" and "good-bye!" of a human toddler and his mom! The first in a brand-new board book series on animal (and human) first words by award-winning author and illustrator Ethan Long.
