The Dracula Duet by Karina Halle

Once there was a man who fell deeply in love with a woman he could never have. When their affair was uncovered she was brutally murdered in front of him, and he discovered he was cursed, doomed to live forever as a vampire.

Over the centuries, he found his love again, and lost her again, until he was so broken he gave up on love entirely, sinking into the depths of depravity, losing his humanity.

Then one day, she came back into his life. A student of music studying under him at the conservatory in Venice, Italy where he was a professor. But even though he found her beautiful and intriguing, he didn't recognize his fated mate at all.

Because this time she had to hide her true self.

This time she came back as a witch, whose destiny wasn't to love him...but to kill him.
