Kiss of night

the long version

Centuries ago, Raphael was a blasphemous knight who fought in the Crusades purely for his own mercenary benefit, and to satisfy his taste for killing. Now, condemned for his evil passions and hypocrisy, he wanders the earth a vampire, cursed with first-hand knowledge of the supernatural world he once denied existed. The powerful relic he still possesses from his days as a Crusader has been stolen by a rival vampire who has recruited an army of soulless underlings to aid him in spreading evil. At the time he learns this, Raphael has been hunting this vampire for nearly a century, and it seems the final battle is destined to take place in Prague.
