Thirst by Pyotyr Kurtinski

"He has lived - undead in time and space, master of darkness, servant to none. A soulless being cursed by the sunlight, exalted by the night's embrace, he stalks his human prey with little danger of retribution. As old as evil, as wicked as sin, he has the power to strike as a bloodthirst man or a vampire bat. And he will attack again and again, hoping to quench his boundles... Thirst." (from book cover)
