Baby Boos! Boo Who? A Spooky Book by Joan Holub

Joan Holub's attractive little board book takes full advantage of the flap book format in her Boo Who? A Spooky Book.

For little ones already a bit familiar with the usual characters of the Halloween season, the reading experience in this little book comes from the skillful rhymes which pose the question (which some kids can probably answer without the prompting of the object beneath the flap) and the pleasant illustrations of those icons of Halloween.

Scratch and hiss.
Who is this? (black cat)
Who has a wide grin
that is lit from within? (jack-o'lantern)
Who has bony knees
that knock in the breeze? (skeleton)
Who sleeps upside down,
then flies around town? (bat)

The descriptions get a bit more advanced as they go on to include spiders, a mummy, and a werewolf. A bonus is that all suggest possible costumes that the young reader may encounter during the season, making them much less scary to meet when trick-or-treat time rolls around in real life.

The final flap has the best surprise.

Who's that hiding?
Who could it be?
Take a look inside
and you will see!

Beneath the last flap is, of course, a mirror. Boo Who? It's you!

Although the flap is a fragile format for small hands, Boo Who? makes such good use of the genre that it's worth the small price of this wonderful little book for the smiles it provides.
