In this “compulsively readable” (Olivie Blake, New York Times bestselling author), unique spin on zombie horror, a brilliant female scientist desperately searches for a cure after a devastating epidemic while also hiding a monumental secret—her undead husband.

How far would you go to save your marriage? For British scientist Kesta Shelley, there is no limit.

Having always preferred the company of microbes, Kesta has spent her life looking down the barrel of a microscope rather than cultivating personal relationships. But that changed when Kesta met Tim—her cheerleader, her best friend, her absolute everything. So, when he was one of the last people in London to be infected with a perplexing virus that left the city ravaged, Kesta went into triage mode.

Though the government has rounded up and disposed of all the infected, Kesta is able to keep her husband (un)alive and hidden with resources from the hospital where she works. She spends her days reviewing biopsy slides and her evenings caring for him, but he’s clearly declining. The sedatives aren’t working like they used to, and his violent outbursts are becoming more frequent. As Kesta races against the clock, her colleagues start noticing changes in her behavior and appearance. She is withering away, self-medicating with alcohol, and has stopped attending her mandated ZARG (Zombie Apocalypse Recovery Group) meetings. Her care for Tim has spiraled into absolute obsession.

There are whispers of a top-secret lab working on a cure, and Kesta clings to the possibility of being recruited like a lifeline. But can she save her husband before he is discovered? Or worse…will they trigger another zombie outbreak?
