"I always thought it would be mankind that would finally decimate itself. I never imagined the world would actually fight back against us before we could destroy it."

No one expected it, certainly not Rory, a twenty-year-old girl who's already got a tough life, and who's about to find things getting a whole lot tougher. Rory finds herself caught in a battle befalling a desolate world, weighing passion and heartache.
Upon finding a chemical that alters not just the brain, but the makeup of living organisms, drastic plans are set into motion by people in a position of higher power. It's a risky move. But without it, the chemical will prove to be catastrophic to mankind.
Selected based on an allele only present in a small pool of the human population, the next thing Rory knows, she's got some fancy new adaptations and is being trained with a group of other survivors. These are the Hybrids, chosen to carry on the human legacy. But will they accept their destiny?
