The Summer Man

the long version

"Amanda Young grew up in Port Isley, a remote seaside community perched on the outermost shores of Washington. She's watched as, each summer, the tight-knit small village braces for the invasion of vacationers seeking refuge from city life. But this year, a new kind of visitor arrives in Port Isley, bringing something most unexpected. Soon after the season begins, a teenage girl's mutilated body is found in a local park. The police declare it a random act of violence, but Amanda's not so sure ... because how can she explain that she had a premonition of the crime just hours before it happened? Or that the neighbors she's known forever inexplicably are beginning to change ... into lustful, violent shadows of themselves? Amanda knows something's not right. And she knows it has something to do with the sinister stranger who's come to town. But can she uncover his dark secret in time to stop him--and in time to save the souls of Port Isley?"--Amazon.com.
