Aliens: Original Sin is a 2005 novel written by Michael Jan Friedman and published by DH Press. It continues the story of Ripley 8 and the surviving crewmembers of the Betty after the events of Alien Resurrection.

Not counting the children's book Cyberantics: A Little Adventure from 1992, Original Sin is the first novel in the Alien franchise not to be an adaptation of a comic book. All subsequent novels would similarly be original stories rather than adaptations.

Publisher's Summary


Nearly three centuries ago, the Weyland-Yutani starship Nostromo investigated what appeared to be a distress call emanating from the barren planet Acheron.

What the crew of the Nostromo found was an alien life form — a hideous, slavering killer, quicker and more powerful than anything they had known before. Only Warrant Officer Ellen Ripley managed to escape with her life, destroying the Nostromo rather than give the monster a chance to reach Earth.

But she hadn't seen the last of the breed. Now, centuries after the death of the original Ripley, her clone has taken up the fight. And she has found, with the help of an android named Call, a brutal hired gun named Johner, and a paraplegic mechanic named Vriess, that there is more to the Alien horror than meets the eye...

In this all-new Ripley novel, best-selling author Michael Jan Friedman asks the unasked questions that pierce the alien mystery to its seething acid-chamber of a heart — leaving nothing in Ripley's universe the same.
