It is about five years after Return Of The Jedi, the New Republic is in control of the galaxy. There are only a few remaining strongholds of the Empire that they have left to defeat. A new leader for the Empire emerges, and has a plan that will return the Empire to its former glory. Suddenly, the New Republic finds itself in a perilous position--they might loose everything they have fought for, to the Empire.
This was one of the first Star Wars books I read, and was one of the reasons I became obsessed with Star Wars. I particularly enjoy books in this universe, that Timothy Zahn writes. He creates a suspense that keeps you turning the pages to see how the plot turns out. You will not want to stop with this book. He also introduces some of my favorite characters: Mara Jade, Talon Karrde, and Grand Admiral Thrawn.
This is the beginning to one of the more satisfying trilogies in the Star Wars Universe. If you are interested in Star Wars, and are not certain where to begin with the plethora of books that are part of this universe, I would strongly suggest beginning here. You will encounter characters you have already become attached to, and become invested in a whole bunch of new ones. I highly recommend starting this trilogy, and discover where in the galaxy you end up.
