Blood Hound by James Baldwin

Alexi Sokolsky is a hunter. A mage and a hitman for the Russian Mafiya, he is a ruthless, fearless savant killer. He is also a chaste mystic who knows, deep down, that the world of organized crime is sick… and that he is sick for being a part of it.

Little does he know just how literal that sickness is. Because even GOD has predators, and Alexi is about to meet them.

While hunting a kidnapped mobster, the key to New York City’s lucrative cocaine trade, Alexi uncovers a deadly conspiracy to hold the world hostage with an ancient being of incredible magical power. Stalked by demons and rival hitmages, he must navigate a black magic minefield of treachery, murder and painful revelation in his pursuit of the truth – truth that forces him to make a decision that could change his life and the course of the world forever.
