Since her night of passion with Sean, Erin hasn't been feeling like herself. Her sense of smell is heightened and dogs randomly bark aggressively at her. Something isn't right, but she doesn't know what it is.

Even more troubling is Sean's sudden disappearance. The morning after their heated night together, he got up and disappeared in to the night while she slept, and now no one knows where he has gone. Could he be the key to unlock her strange experiences?

Erin knows that she must find Sean. He owes her both an apology and an explanation, and she's determined to get them.
