Harvest Rosenbloom has magic in her veins and a second-sight that sets her apart, but at the Bureau's missing persons division, her talents are gathering dust. Stuck behind a desk and drowning in paperwork, she knows she's capable of more, if only her boss would see it.

Everything changes when Harvest receives a desperate, cryptic message from her estranged sister, Hazel. Haunted by years of guilt and missed opportunities, Harvest is determined to make things right this time, no matter the cost.

Harvest teams up with Agent Quinn, a centuries-old vampire who's seen it all, or so he thinks. What starts as a seemingly straightforward investigation brings them into the seedy underbelly of a vampire criminal network to Death's door and beyond. Can they solve the mystery before time runs out, or will Harvest lose her sister forever?
