Misfits.

After the world ends, a new one begins, becomes corrupt, and falls apart again. The Phoenix rises from the ashes, and somehow new societies re-emerge.

(Post-dystopia, because we all know those horrible places are going to be overthrown and fall apart, but then what?)

Meet Silas, a Misfit who has only ever known life in a bunker;
Dahlia, his closest friend, who has loved him her entire life.
And Ixlaina, a lovely, robot-programming mystery, who holds all the secrets of Phoenix- the city that should no longer exist- and some secrets of her own.
