Star Wars (A New Hope) by George Lucas (supposedly)
This book is worse than Splinter of the Mind's Eye. That was like a train wreck: horrible, but I just couldn't stop reading. This was just plain bad, and I had to make an effort to see it through to the end. For a slim book, it felt a lot longer than it was.
It was instructive, however. For some fine examples of over-writing you can't go past this book. "A lung-searing miasma of carbonized component filled the air, obscuring everything." You mean, smoke?
To be honest, there's not a lot to say about the book. It's badly written, and adds nothing to the story that the movie hasn't already shown. It is interesting to see how the history of the universe has shifted since the first film came out. The small backstory given in this book reveals that while Palpatine did name himself Emperor, he then became a recluse, and it is the barons and officials around him who are tearing the galaxy apart and giving the Empire a bad name.
The biggest shift appears to be regarding Anakin's life. In the new movies, he spends hardly any time at all on Tatooine, yet in the books everything appears to indicate he spent a significant portion of his life there, not to mention that everyone was very chummy with him. It's a very different feel.
Other than that, this book really isn't worth your time.
Verdict: Maybe read a few chapters if you want some bad writing. Otherwise there are much better things you could be doing with your life.
