Skip this & buy the omnibus version
I fondly remember buying this novel as a paperback and reading it the day before the film opened -- my best friend was going with me, and he had to work that Friday night -- I really enjoyed the book and McIntyre's novelization was quite enjoyable, especially read before seeing the film.
But my recommendation would be to skip this single-story edition and get McIntyre's "Star Trek Signature Edition: Duty, Honor, Redemption", which contains her novelizations of "The Wrath of Khan", "The Search for Spock", and "The Voyage Home", all for just a few dollars more than this single edition.
Not as epic as the movie
As far as movie novelizations go, this one wasn't bad. The story flows nicely, and there was some added insight to the characters, such as the relationship between Scotty and his nephew Peter. It was also interesting to learn a bit more about Kirk's spectacles (apparently they are nearly extinct in the future). My only bone to pick with the book is that the epicness that made the movie Star Trek II: The Wrath of Khan great is missing. The classic line of Kirk saying "KHAAAAAN!" was diminished to a simple "Khan!". Other famous words of dialogue from the movie are changed as well. Khan's last words, "From Hell's heart..." is an example, as well as Spock's line "The needs of the many...". Perhaps not a big enough change to make a difference to casual fans, but for me, as an avid Trekker, I can't help but notice the differences and point them out.
