Star Wars: From the Adventures of Luke Skywalker
There are no original books, they first made the movies, and then wrote some adaptations that really isn't worth the read.
was actually first published in 1976, prior to the theatrical release of Star Wars
. I can't recall the novelizations of The Empire Strikes Back
and Return of the Jedi
all that well, but the prologue and other details in the novelization of the first film do make it worth reading.
prety much this with the exception of Splinter In the Minds Eye which was written before the first movie but they used an early draft of the script as guidance.
While Splinter of the Mind's Eye
borrowed some elements from early Star Wars
script drafts (the Kaiburr Crystal, for example), it was not
written before Star Wars
. It was written to provide the basis for a low-budget sequel if the first movie was not financially successful, and thus was published in early 1978.
