Dr. Merlin Tuttle and his colleagues at Bat Conservation International aren't scared of bats. These bat crusaders are fascinated by them, with good reason. Bats fly the night skies in nearly every part of the world, but they are the least studied of all mammals. As the major predator of night-flying insects, bats eat many pests. Unfortunately bats are facing many problems, including a terrifying new disease. White-nose Syndrome is infecting and killing millions of hibernating bats in North America. But Dr. Tuttle, with the help of his fellow bat scientists are in the trenches—and caves—on the front line of the fight to save their beloved bats.

"Whether describing the physics of echolocation or the present crisis of white-nose syndrome, Carson encourages readers to rethink stereotypes about creatures once scorned as flying vermin and shows how intricately their survival is tied to our own."—Booklist, starred review 

"A strong scientific look at a unique and often unloved mammal and the scientists who happily investigate them"—School Library Journal
