Toxic

When a Six saved Kale's life the night of Sumrun, she warned there would be consequences. A trade-off. Something taken for the life they gained. But Dez never imagined she'd lose the one thing she'd give anything to keep... And as if it's not enough Dez finds her immunity to Kale fading, the Six brought in to help Kale learn to control his killer touch starts drooling on him the moment they meet. Worse than that? Jade can touch Kale. But bimbo Barbie is the least of Dez's problems.
After Dez and Kale got away at Sumrun, her father lost not only his most powerful weapon but an important piece of the Supremacy project. Forced by Denazen to remedy the situation, he poisons Dez and offers her a choice—surrender to Denazen for the cure...or die. Determined to find a solution that doesn't involved being bagged and tagged—or losing someone she loves—Dez keeps the poison a secret. But when a rash of Denazen attacks hit a little too close to home, Dez is convinced there's a traitor among them. Jade.
Sacrifices, broken promises, and secrets. Dez will have to lay it all on the line if there's any hope of proving Jade's guilt before they all end up Residents of Denazen. Or worse, dead...
