Betrayal is the first of a 9-book series called Legacy of the Force. the rest of the volumes will be published between August 2006 through 2008.
i would have liked this a lot better if there wasn’t too much going on. although the central figure is Jacen Solo, all of the other events surrounding his particular path are also important. thus, the story and by extension, the readers, end up planet hopping all over the galaxy. in fact, that’s how Allston divides up subsections of each chapter—by where they take place. for example, the first chapter starts with something happening on Coruscant, then there’s a transition to something taking place on Adumar, etc. it’s easy to get lost.
although there are numerous subplots-all of which are very good-i wanted to be able to read more about the characters in those parts of the story. since the next book will be written by a different author, i hope we’ll still get to see some of these “minor” characters because they’re so interesting.
it isn’t necessary to have read every single book/comic that takes place between Episode VI and Betrayal, but i highly recommend that people read The Corellian Trilogy first, which includes Ambush at Corellia, Assault on Selonia, and Showdown at Centerpoint.
