FOLLY, by Laurie R. King

A magnificent stand-alone tour de force by this prolific and varied author. Rae Newbourn, famous woodworker, bereft wife and mother, and recently released from a mental hospital, chooses to isolate herself on a deserted island in the middle of Washington state's San Juan Straits. Bequeathed to her to her by the estate of her viciously judgmental grandfather, Rae is determined to ignore her panic attacks and paranoia, and single-handedly rebuild the house that her great uncle had built in the 20's. As always, a mystery reveals itself, and Rae must question exactly how paranoid she really has been. It's a great 5, I think it's perfect for a book club.
