Some grudges live forever, and the worst enemies are the ones you didn't know you had… Alpha empaths are dying, executed by an assassin who leaves no psychic trace. Zara Itani derides the mystery as sloppy investigation until Danyael is injured by the assassin’s bullet. If he died, his empathic death throes would have driven everyone within ten miles to suicide. The only solution is to imprison Danyael beyond the reach of assassins, damning him to physical solitude and emotional isolation. Zara, however, bets on her ability to use Danyael as bait to draw out the murderer. Kill the assassin, end the threat, right? But nothing is ever easy in a world transformed by the Genetic Revolution. Sins of the past transcend decades and centuries to coalesce into a threat no one can contain. A vigilante driven by hate demands absolute vengeance—the suicide of millions of innocent people—and it will begin with Danyael’s death. This is a standalone futuristic thriller set in the world of the Double Helix.
