You should know before you read this I'm a Star Wars fan. A fan of the old films much more than the new, but not a convention-attender or anything like that.
So, on with the review.
[spoilers - if you don't want to hear anything about the story skip this paragraph]
The story essentially covers Luke's beginning of the Jedi academy, showing how he begins to find new Jedi - and his adventures in doing so. Beside Han travels with Chewie to Kessel, where he is held prisoner. Upon escaping, young force-user Kyp in tow, they once again are taken prisoner. Leia doesn't do much other than political affairs and look out for the kids.
[spoilers end - now you can read again]
Kevin Anderson does a good job of capturing the Star Wars feel, appealing simultaneously to the old trilogy - even bringing in lines from time to time - whilst progressing the story and bringing in new elements.
That said, the book does not add a huge amount to the saga. Luke would be the only one who seems to get any character progression and pages are often spent writing about storylines the reader will not care about.
I would recommend this book to those already aquainted with and interested in the Star Wars universe, it will offer little to anyone else.
