In this book, we see Star Wars:  A New Hope from Luke Skywalker's point of view.  According to the book, he was keeping a journal of all the events, even when he's on the Millennium Falcon.  This series bit far-fetched in my opinion but it offers some insight into Luke's mindset throughout the movie and some background on his life before the movie.  I didn't mean for this to turn into a review, but the book gives a small excerpt on the back instead of a summary.
