Freya (not her real name) is on the run. She's the last remaining participant of a medical research study whose doctors and patients all suffered "accidental" deaths. Someone powerful doesn't want the world to know that xenografts have the potential to protect humans from disease. Hiding in plain sight has its advantages but attending a rough new high school infested with xenofreaks is not one of them.Dan has no idea why he's so fascinated by the new girl, but he does know his visceral response to her scent isn't remotely normal. He hangs with the xenos, so avoiding her is easy until someone comes looking for her and she bolts. She doesn't want his help, but she needs it, and he needs to figure out what it is about this girl that makes him crazy.
