Bloodline (The Reaper Saga) (Volume 1)

As an executioner for the Empirical Police, Sven Nulis’s job is simple: hunt paranormals who prey on humans. But someone has other ideas for the man known as the Reaper. A killer prowls the Empire’s streets, leaving mauled corpses in its wake. Bodies addressed to the Zieken, a species of half-human that shouldn’t exist, are being delivered into Sven’s path. In addition to the macabre gifts, the Reaper is being stalked by an agent from the other side who knows him well enough to creep inside his dreams. Elbows deep in crime scene photos and cryptic messages, Sven has to discover how he’s connected to the case while more victims surface. As the murderer draws closer, the Reaper finds himself deadlocked with a force far greater than the average prey. And the answers he seeks may hinge on the secret power living in his blood.
