It's supposed to come out sometime in Fall of 2010. I'm guessing around August, 或者 late September. There is no book name currently available to the public.
Disregard the 2 above. No one knows yet when book 3 is coming out. (sorry, i know i can't wait either!) But some sites say it will be coming out in May of 2010, and others say Fall 2010. No one knows which 日期 is true yet though. It is not official, but as of now, book 3 will be called "The Victors."
