Stranger Beside You...is that the Ann Rule book about Ted Bundy? Nope, that is Beside ME, isn't it? Whatever, I read it years ago. It is creepy. Why would they offer an old book? Never mind me, I'm blabbering.
And, I do agree, FB is great for the freebie kindle books. You'll never be able to read them all.
Some of the ones I've read are really good.
