Ryan Alexander has been left physically and mentally battered from contact with the species that spawned her Kind. Although her power has increased exponentially, she has little control over her new abilities. Worse, as memories of the origins of the Old Ones surface, her own memory begins to suffer. Those closest to Ryan watch her internal battle with growing unease as she herself wonders if she has become a threat to all that she loves. When she begins seeing creatures that no one else sees, she does not know if her guilt is manifesting as illusion, or if she is simply losing her mind. Dr. Susan Ryerson monitors her friend's increasing instability. She is not certain if Ryan has been sickened by blood contact with the parent species, or if this is simply the aftermath of Ryan's torture and captivity. But it was a blood mutation that created Ryan and her Kind, giving rise to the myth of the vampire, and now Susan wonders if a second transition is occurring, if in fact Ryan is undergoing a second Change. Which brings to her mind a most terrifying question...into what? Book #4 in the Blood Legacy series.
