Lane barely survived her first journey to the Feral Zone. The forbidden, overgrown landscape east of the Mississippi River was abandoned years ago when a virus spread through the population, bringing civilization to its knees.
But Lane has crossed the quarantine line, and she knows the truth. There are survivors on the other side of the wall - people who were not killed by the virus, but changed by it, their bodies warped to display a variety of animal traits. In the most severe cases, their minds are warped as well, leaving them barely human.
Lane volunteers to return to the Zone as part of a humanitarian aid mission. But she has a darker, secret purpose. Someone she loves has been infected, and she once made him a promise: If he ever goes feral, Lane will be the one to put him down. Now, Lane fears that the time has come.
