The first four novels in the Jolie Gentil cozy mystery series, by Elaine Orr, are available in a single package. I'm not sure what to make of the pricing. If you want to buy the four books separately, they'll cost you about eight dollars, but the "Free" package doesn't seem to be related to the Summer Sale.
I think I've read eight of these so far, and they're very good. They are cozy mysteries -- straight up, with no cats or paranormal elements -- set in a small town on the (New) Jersey shore. They're good stories with good characters.

Some of her other stories are included in the sale as well, including the collection of books five through seven.
