The end of the world is bigger than love

"Identical twin sisters Summer and Winter live alone on a remote island, sheltered from the fallout of a mysterious event that has laid waste to the rest of the world. They survive on rations stockpiled by their father and spend their days deep in their mother's collection of classic literature--until a mysterious stranger upends their carefully constructed reality. At first, Edward is a welcome distraction. But who is he really, and why has he come? As love blooms and the world stops spinning, the secrets of the girls' past begin to unravel and escape is the only option"--Back cover.
