Nuclear war, dystopian unrest, a genetic mutation that divides twins in life and unites them in death--the refreshingly nuanced (Booklist, starred review) first novel in award-winning poet Francesca Haig's richly imagined and action-packed post-apocalyptic trilogy is poised to become the next must-read hit (Kirkus Reviews, starred review).

Four hundred years after a nuclear apocalypse, all humans are born in pairs: the deformed Omegas, who are exploited and oppressed, and their Alpha twins, who have inherited the earth--or what's left of it. But despite their claims of superiority, the Alphas cannot escape one harsh fact: whenever one twin dies, so does the other.

Cass is a rare Omega whose mutation is psychic foresight--not that she needs it to know that as her powerful twin, Zach, ascends the ranks of the ruling Alpha Council, she's in grave danger. Zach has a devastating plan for Omega annihilation. Cass has visions of an island where a bloody Omega resistance promises a life of freedom. But her real dream is to discover a middle way, one that would bring together the sundered halves of humanity. And that means both the Council and the resistance have her in their sights.
