The Dog Stars By Peter Heller

Hig somehow survived the flu pandemic that killed everyone he knows. Now his wife is gone, his friends are dead, and he lives in the hangar of a small abandoned airport with his dog, Jasper, and a mercurial, gun-toting misanthrope named Bangley.

But when a random transmission beams through the radio of his 1956 Cessna, the voice ignites a hope deep inside him that a better life exists outside their tightly controlled perimeter. Risking everything, he flies past his point of no return and follows its static-broken trail, only to find something that is both better and worse than anything he could ever hope for.
