Seductive Suspect by Thea Landen

When Veronica Campbell agrees to take her sister’s place at a murder mystery weekend getaway, she has no idea what’s in store. The events at the mountaintop lodge get off to a good start, especially when she meets Adam, the handsome man staying in the room next door. By the end of the first night, however, the role-playing games take a dark turn when one of the participants is killed for real.
Violent storms and sabotaged cars trap the guests at the lodge with no escape. Frightened and surrounded by strangers, she not only has to stay on guard against the danger lurking in every corner, but fight her attraction to her sexy neighbor.
One by one, the number of guests dwindles as the murderer strikes. The longer they survive, the more Veronica worries she’s falling for Adam. Can she trust him, or has she wound up in the arms of a killer?
