Radu's quest for a sacred artifact transforms him into an immortal vampire, forever seeking both companionship and blood to survive through the ages.

Stolen by crusaders on the night of his birth, he has no knowledge of his bloodline: his mother is a demon; his father is a vampire. Trained and exploited by a brotherhood of mystic monks to slay all enemies of the church, fate brings him back one night to the castle of his father, armed with the monster-slaying Sword of Laertes, to destroy the vampire Vladislas and reclaim a holy relic: The Bloodstone. The events of that night turn Radu from a noble man into a vampire with no master, setting him on a centuries-long quest for sustenance, and companionship, for the treacherous one who stole him from the sun, and for the Bloodstone he hopes will bring him peace. Spanning 500 years in the life of the vampire Radu Vladislas, this long-anticipated prequel to the Subspecies series chronicles Radu's descent from a noble warrior for the Church to a depraved creature of the night.
