It's been a long time coming (I think the 11th book in the series), but through this unique addition to the Star Wars universe we are finally shown a great understanding of the Yuuzhan Vong. Jacen Solo has been captured and tortured mercilessly, or so it first appears, under the watching eyes of Vergere. However, what becomes clear is that she is teaching him the ways of the Vong - an understanding of their way of life that will ultimately lead him to becoming the most powerful Jedi in the galaxy. This book isn't always easy reading - some of the imagery and scenarios are far more haunting and dark than in any other SW book - but it is always compelling. It's so different from any other. There are no space battles, no Jedi in-fighting, no political squabbling. It is all about Jacen learning the truths of the invasion, of himself and of the wider implications of the Force. There are only four major characters in the entire novel, but it never ceases to interest. Although it is deliberately unclear whether Jacen, or Vergere, or both are the traitor of the title until the end, the climax is thrilling, including the loss of an important character in a way that is both sad and gratifying at once. Stover has done a great job here in creating a perspective on both sides of the conflict, while also revealing much about the Force that is far more interesting than Lucas has ever revealed in the films. My only slight concern is that it seems unlikely that any other book to follow this will live up to it, as it makes the repititive space battles and planetary losses seem almost dull in comparison.
