How far would you go for the one you love? How much of yourself would you sacrifice? Trapped on a decaying Earth and cut off from the rest of the Universe, humans are no longer allowed to leave their planet. Break this one law and you die: a penalty enforced by flyers, aliens who look like angels of long-lost religions. Michael, the flyers' leader, is the Punisher who carries out every public execution. Adam, a young human with near-perfect memory, is committed to rebuilding Earth and a true believer in the flyers' dominion. While Adam's support for flyers isn't a secret, his deep love for Michael is. Not even Michael knows, for his kind never take human lovers, and to Adam, they are too far above him to reach. In his broken and unwelcoming world, Adam's love can only lead to pain, loss, and disaster. Yet there is no force in the huge expanse of stars and galaxies that can stop Adam from following Michael to the end of existence. Not even Adam's own beliefs.
