Lifeblood (Bloodstained Archives) by B. W. Green

These books come signed by the author.

Dr. Ethan Dalton, a geneticist from New York City, never believed in legends–until one became his reality. A work conference in Bucharest, Romania, takes a dangerous turn when his colleague Jack convinces him to explore the countryside. What begins as a fun trip to the mountains spirals into a treacherous encounter that will alter the course of his life forever.

Abduction. A world he never knew. A truth he can’t escape.

As Ethan struggles to escape back to his old life, he faces an even greater question–can he ever go back to who he was?
Or is everything he believes about himself, and the world, a lie?
