This monster seems to be especially attracted to one woman, Jessa, who has been left to live alone in her family's farmhouse. And, it turns out, Graf is also attracted to her. After he saves her life, he guilts her into letting him sleep (or, hide from the sun) in her basement. Together, they realize that things are escalating and their choices are to either find a way out of town or a way to kill the monster.
I think this is the first Jessica Armintrout I've read, and I'm sure I'll read more. It was a nice break from some of the heavier books I've been reading.
