The Final Prophecy by Greg Keyes

In this book there was a lot less jumping around and fewer subplots than in the past few New Jedi Order books. Tahiri, Corran, Nom Anor, and some rouge Yuuzhan Vong go to Zonama Sekot, where we (the readers) get this close to finding out what's going on, and then the character who's figured it out dies. There's another battle at Bilbringi, but you can tell that the plot's just marking time while the Zonama Sekot stuff happens. A quick read. I must say, I'm looking forward to seeing how it all turns out in the last book.
