Wicked Prey by John Sandford comes out on May 12, 2009.
 

If you are too impatient to wait all that time you can read the first chapter of Wicked Prey here-- http://www.johnsandford.org/prey19t.html

I have read most of these Prey books except for the last couple of ones. It seems when I buy a book, it makes me less likely to actually get around to reading it. And, I got these later Prey books from various book clubs.
