In the fourth installment of Dragonbreath, Danny and Wendell discover a bat trapped in the neighborhood swimming pool.

After rescuing it and consulting with Danny’s Mom, they head off the the Central American Rain Forest to consult with Danny’s Cousin, who studies bats, and is on the trail of the legendary Giant Bat Camazotz! What follows is, of course, an adventure only Danny and Wendell could have, and only Ursula Vernon can write and illustrate.
