Louis Daniel hates it when Mama treats him like a baby. But when Hurricane Katrina blows through the Gulf Coast on a fateful August night, Louis feels like a little kid again.

With no time to gather their belongings--except Louis's beloved horn--Daddy leads the family from their home and into an unfamiliar, watery world of floating debris, lurking critters, and desperate neighbors heading for dry ground.

Taking shelter in the already-crowded Superdome, Louis and his parents wait...and wait. Conditions continue to worsen and their water supply is running out. When Daddy fails to return from a scouting mission within the Dome, Louis knows he's no longer a baby. It's up to him to find his father--with the help of his prized cornet.
