"First, do no harm." Blake Ryan swore that oath to become a doctor. Ironic, given that he spent most of his thousand year life sucking souls out of other immortals.

Things are different now. Using regular shots of morphine to keep his inner monster at bay, Ryan has led a quiet life since the Second World War. His thrills now come from saving lives, not taking them.

Until a plane crash brings Aleria into his hospital. Her life is vibrant. Crack to predators like him. She's the exact sort of person they would hunt, and thanks to a severe case of amnesia, she's all but defenseless.

Leaving Aleria vulnerable isn't an option, but protecting her means unleashing his own inner monster. Which is a problem, because his inner monster wants her dead most of all.
