Fifty years after the Singularity, the world is divided into two populations locked in a cold war: Synthetic Citizens, or Syns, human-computer hybrids with extraordinary enhancements and potentially infinite lifespans; and Originals, the individuals who did not merge their bodies with the machines.

But the decades-long battle between Original and Syn is almost at an end, because the Originals are on the verge of extinction. One of the only young Originals left in the world, Ere, knows he might someday be the very last of his kind. But when he meets a beautiful, powerful Syn girl called Ever, he questions everything he's ever been told about his lifelong enemies.

Original Syn is a rich, dangerous world of family secrets, free will, forbidden love, and all of the unexpected peril that arises when aggressive technology meets stubborn humanity.
