FAITHLESS is a book in Karin Slaughter's Grant County series. I’ve read most of her books, which is a testament to what a great writer she is, particularly of mysteries/thrillers. But I read them as I find them in used bookstores, so out of order, and I still enjoy the heck out of them. But good for you if you can read them in order.

The three main characters in this series are Jeffrey Tolliver, Grant County’s police chief; Sara Linton, Tolliver's ex-wife, a pediatrician, and Grant County's coroner; and Lena Adams, a Grant County detective who works for Tolliver. All three become involved in the workings of a church (or is it a cult?) after Tolliver and Linton stumble across the body of one of its members in a coffin buried in the woods. She had been buried alive. Did she suffocate? Or was she poisoned? Have other church members suffered the same fate?

Both Tolliver and Adams investigate, while Linton mostly acts as Tolliver's sounding board, although she too becomes involved to a lesser extent. They find a church run by a particular large family. Now can they find out why the dead woman, a member of this family, was buried alive and who did it? As a result of their investigation, they find so much more about the church and about the family that runs it.

Because I’ve been reading Slaughter's two series out of order, I’ve already read the next book, BEYOND REACH. Luckily, I have it in my bookcase so I can skim through it to remind myself of what happens next.
