"The plot of this books sounds like the perfect adventure for a noble hero: a dangerous journey with a cryptic map and a trusty companion. But here's the catch: the hero is an undersized bat.... The greatest strength of this story lies in its fast-paced, cliff-hanging action and its setting within the hollow trees and bell towers of the bats' monochromatic nighttime world. Recommend this one; they won't be disappointed."
