Review Detail of RexHarris in I Became a Progenitor Vampire

I really loved the world back ground of this story. A hiden vampire with his own faction. But i couldnt enjoy this novel for two main reasons. The first is that he can return to earth. It really kills it for me because there is no real suspense because he cam literally just leave. The second is he doesnt act like a vampire at all. He suposedly gains the memories of a vampire mage who has lived for centuries but it doesnt seem to affect him at all.
