Hold - Zannie Adams Wow, I've been on a run of really good books and this one is right up there, just ignore the cover.

In this future you are sent to prison for life for everything from trespassing to murder. Riana is sent because although she had permission to perform an archeological dig, she went outside the authorized area. She's told when she gets to the prison, where it's pretty much a dumping ground where the prisoners have control of their cells that she should find the strongest man she can and have him take care of her. She sees Cain as they circle before she taken off the carrier and thinks of all the animals he looks the most sane. They start out as companions for convenience and safety and then start to develop feelings for each other. Now they have to get out. Great book, lots of terrors and small portions when there is kindness. I would definitely recommend this book.
