Reprisal

Mitchell Smith writes deceptively quiet, outwardly civilized thrillers about people we can identify with--people whose lives are suddenly ripped apart. He's fascinated by the way his characters react to stress, by how much pressure they can absorb before they either break or change into another kind of person.
In Reprisal, Joanna Reed, a poet and professor, is sorely tested by various demons. She battles breast cancer, and then her husband Frank, an experienced sailor, drowns in the Atlantic Ocean. Joanna tries to work out her grief and pain as she has always done, by spelunking in dangerous caves. Meanwhile, her elderly father is burned to death in his cabin in the woods--another accident.
We quickly find out that a strange young girl named Charis--the college roommate of Joanna's daughter--is connected to the deaths. Tough and endlessly resourceful, Charis wants to destroy Joanna's life as reprisal for a past grievance. It takes the equally smart but grief-slowed Joanna some time to realize what's happening, but Smith is so good at getting into her mind and soul that we can easily forgive this small lapse. He also rewards our patience with an ending that is both terrifying and sadly inevitable. --Dick Adler
