The acclaimed author of Sniffer Dogs details the successful efforts of scientists to bring threatened animals back from the brink of extinction, perfect for animal lovers and reluctant nonfiction readers. With full-color photography.

How could capturing the last wild California condors help save them? Why are some states planning to cull populations of the gray wolf, despite this species only recently making it off the endangered list? How did a decision made during the Civil War to use alligator skin for cheap boots nearly drive the animal to extinction?

Back from the Brink answers these questions and more as it delves into the threats to seven species, and the scientific and political efforts to coax them back from the brink of extinction. This rich, informational look at the problem of extinction has a hopeful tone: all of these animals' numbers are now on the rise.
