Once she arrives, she discovers the truth is stranger than fiction, and Ara wonders if she's made a huge mistake . . .

Kaden

Sam

Has hooked up a rigged electrical system, blasting away the silence with music, feeling almost normal since he nearly lost his life. He doesn't know where Kaden and Ara are, and when he meets a mysterious girl named E, they embark on an adventure that will bring all of their lives crashing together . . .

All three must uncover the secrets of The Last City if they have any hope of getting out of this apocalypse alive.
