A mortal human with a knack for healing creatures her own kind can’t even see, Liesel needs to find the source of the outbreak before it’s too late. Working with the inscrutable vampire lieutenant, Jax Halloran, the pair are about to uncover secrets that are far more dangerous than either of them could imagine. At the same time, all her evenings spent moonlighting in the underworld are having consequences for normal life as a student and for her relationship with her human boyfriend. What she really could use is some time to figure things out. But time is the one thing Liesel doesn’t have.
