Bryn Davis was killed on the job after discovering her bosses were selling a drug designed to resurrect the dead. Now, revived by that same drug, she becomes an undead soldier in a corporate war to take down the very pharmaceutical company responsible for her new condition...

After dying and being revived with the experimental drug Returne, Bryn Davis is theoretically free to live her unlife—with regular doses to keep her going. But Bryn knows that the government has every intention of keeping a tight lid on Pharmadene's life-altering discovery, no matter the cost.

Thankfully, some things have changed for the better; her job at the rechristened Davis Funeral Home is keeping her busy and her fragile romance with Patrick McCallister is blossoming—thanks in part to their combined efforts in forming a support group for Returne addicts. But when some of the group members suddenly disappear, Bryn wonders if the government is methodically removing a threat to their security, or if some unknown enemy has decided to run the zombies into the ground...

Already addicted to the pharmaceutical drug that keeps her body from decomposing, Bryn has to stop a secretive group of rich and powerful investors from eliminating the existing Returné addicts altogether. To ensure their plan to launch a new, military-grade strain of nanotech, the investors' undead assassin — who just happens to be the ex-wife of Bryn's lover Patrick — is on the hunt for anyone that stands in their way.

And while Bryn's allies aren't about to go down without a fight, the secret she's been keeping threatens to put those closest to her in even more danger. Poised to become a monster that her own side — and her own lover — will have to trap and kill, Bryn needs to find the cure to have any hope of preserving the lives of her friends, and her own dwindling humanity...
