Laplace's Demon

Laplace’s innocent blood has awakened a centuries-old curse—a Japanese demon sworn to wreak havoc on this world.
The seductive powers granted by the demon’s sword help Laplace cut a swath through the Paris underworld. But with the rising body count, the demon’s strength grows. Its desire for blood will never be quenched. And once Laplace’s loses himself completely, it will never be stopped.
