The Dog Stars by Peter Heller follows the journey of Hig, a man who somehow survives the flu pandemic that claimed the lives of his wife, his friends, and pretty much everyone else he knows. While living in the hangar of an abandoned airport with his dog, Hig receives a transmission through his old radio, and he seeks out the source of the message, though he's not sure whether it came from a rescuer or a threat.
