The Deathtaker — S.L. Baum

Krista can smell disease and decay. She walks through life being able to pinpoint what is wrong with the people around her, and can tell whether or not they have long to live. She's spent the last few years moving from town to town, looking for someone to help, someone who needs a second chance at life. But she didn't plan on staying in a small town, and she didn't plan on finding someone to love… in fact, she didn't plan for anything that Cedar Creek had in store for her.
