All they can do is live day to day...

Felix Ingesson has returned to his duties as the Chaos's engineer with Zander Anatolius, his ex-boyfriend-turned-broken-super-soldier, at his side. Hope means something again. But there's nothing Felix can do to battle the alien poison flowing through Zander's veins, or his imminent mental decline. With each passing day, the side effects of Zander's experimental training are becoming more difficult to ignore.

When the ruthless Agrius Cartel seeks their revenge—including an ambush and an attempt to kidnap the Chaos's crew—Zander is pushed over the edge. He can no longer hide his symptoms, nor does he want to. But hurting Felix when he's not in control of himself is Zander's worst nightmare—when it nearly happens, he agrees to seek help. Even if that means trusting the unknown.

As Zander places his life in alien hands, Felix appoints himself his lover's keeper. And though he tries to be strong, he can't ignore the fact that he might lose Zander...forever this time.
