Backlash by Aaron Allston

This book takes Luke, Ben, Han, and Leia back to Dathomir. I enjoyed seeing Luke and Ben interact with other Jedi again, and I'm getting increasingly interested in this lost tribe of Sith. It was definitely a very middle-of-the-series book: there are lots of plot lines meandering around that don't seem very close (at all) to resolution (and the what made Jacen Solo go bad thread seems to have been dropped, for the moment at least, entirely). So, we'll see how the series develops from here. I also like the development of Allana's personality.
