The novelization of all three films is in this omnibus.
I found the Star Wars and the Return Of The Jedi stories the best of the three. There seemed to ba a little bit of consistency problems with the three novels as in Jedi, Chewie, Artoo, and others that speak different languages were formatted and written differently than the other two novels. Also in Jedi is the first time See-Threepio is written as C-3PO.
Other than that they are pretty good. What I usually like about reading good novelizations is being able to read about what chatacters are actually thinking. There is that here as I get to know what Vader thinks, and Luke.
Some intersting new stuff is introduced that you barely notice in the films (if they were in the films at all). For example Luke's best friend on Tatooine.
If you are a Star Wars fan I recommend them. They are short tiny novels (all three are just over 400 pages total) so it's not going to take forever and they are easy reads.
