Has been announced!
Once I finished the fourth book, and I thought it was the final, I did some snooping.
This book has been months in the making, so here's the Goodreads page. Which is a big deal, to a book nerd like me.
Once the cover is final, I'll probably post it.
Oh, and it's called, Out of Sight, Out of Time. (LOVE it.) And releases on March 20 of 2012.
(oh, also, if you didn't know, this is written by the awesome Ally Carter.)
