Edge of Evil by J. A. Jance. I buy most of my books at our semi-annual library book sale, 50 cents for hardbacks and 25 cents for paperbacks. I buy enough to last until the next book sale then take back the ones I have read and buy more. Cheap way to read. There is always a good selection. My only problem is that I sometimes buy one or two that I have already read and turned back in. Oh well, it is for a good cause.
