I really enjoyed Alien 3. It is very close to the movie as it should be, and of course explains everything in much greater detail. It is book #3 of the Alien quadrilogy. As I recall, the movie Alien 3 is labeled #5 which doesn't make sense. Sigourney Weaver as Lt. Ellen Ripley shines through in both the book, and the movie.
Here even the wind screams. Abondoned hulks of machinery rust in the colorless landscape. Dark, oily seas beat against a jagged black shore. And the remnants of a reentry space vehicle crash into the rough waves. In it sleeps Ripley, a woman who has battled the Enemy twice. It killed her whold crew the first time. The second time, it slaughtered a spaceload of death-dealing Marines. Now, on this prison planet that houses only a horde of defiant, captive men, she will have to fight the ultimate alien horror one more time before it rips apart a whole world...
