Olivia 'Liv' Moore, a medical resident on the fast track to a perfect life, until she's turned into a zombie. Now stuck between half-alive and undead, Liv transfers to the city morgue to reluctantly access the only thing that allows her to maintain her humanity, human brains. But there are side effects to Liv's new diet. With each brain she consumes, she experiences flashes of the corpse's memories including, at times, clues as to how they were killed. Her boss, a brilliant but eccentric conspiracy theorist, encourages her to embrace this gift and to work with an eager, unproven homicide detective to help solve these murders and quiet the voices in her head.
