Legacy of the Force: Betrayal marks the beginning of a new 9 book series taking place ten years after the 19 book New Jedi Order series and about four years after the Dark Nest Trilogy that bridges the gap between the NJO and LotF. Betrayal in my opinion is a far more satisfying opening to LotF than Vector Prime was for the NJO, this I think hinges on how much I enjoyed the Dark Nest Trilogy and how it set the galactic scene after the Yuuzhan Vong war and how it sorted out a number of key issues so LotF could hit the ground running. This however is not to take anything away from Betrayal itself, this book is excellent in its own right with Aaron Allston crafting a compelling and extremely enjoyable story.
Betrayals plotline is centered around the growing tension between the Corellian system of planets and the Galactic Alliance, with a Jedi Order that is continuing to grow and become an important part in guarding the peace and security of the galaxy. The Corellian system on the surface is simply wanting concessions from the Galactic Alliance but with Thracken Sal-Solo as Corellias(the planet) Chief of State, Centerpoint Station and Sith thrown into the mix things are anything but simple. However this latest galactic incident has a lot of implications for the Skywalker/Solo families as Han solo and Leia gravitate towards the side of the Corellians while the rest of their family are Jedi Knights duty bound to protect the Galactic Alliance. This plot is beautifully handled providing anything but a clear cut conflict as both sides have valid concerns and are being manipulated from behind the scenes by the true enemy. The books highlight is the focus upon Jacen Solo now an active Jedi Knight for the Order and his informal apprentice Ben Skywalker as they get drawn into this conflict which leads to a simply amazing turn of events which I wont dare spoil for anyone.
Aaron Allston provides an exciting adventure full of action and humor that further convinces me that this is going to be a superb series. My only complaints are that I would have liked to have seen more Jedi Masters such as Saba Sebatyne, Kyle Katarn, Cilghal etc and the Jedi Academy on Ossus but those are very minor things. LotF: Betrayal left me like the Dark Nest Trilogy did, desperate to read what comes next.
This the paperback version of Betrayal also has an added bonus of containing two short stories. These two stories are by Karen Traviss and although they do not tie into the Legacy of the Force storyline they are both excellent. They are called "In his image" and "A two-edged sword" and focus upon Darth Vader in the years following Revenge of the Sith.
