Aliens

A direct sequel to Aliens and Alien 3—Weyland-Yutani, the Colonial Marines, and Bishop's creator all pursue the android for the deadly Xenomorph data contained in his brain.  Written by T. R. Napper, award-winning author of the acclaimed 36 Streets, whose explosive work explores the artificial intelligence and what it is to be human.

"Do me a favor. Disconnect me. I could be reworked, but I'll never be top of the line again. I'd rather be nothing."
Lance Bishop, model 341-B, on Fiorina 161

The USCSS Patna has been found.

Although the synthetic Bishop asked to be shut down forever, his creator has other plans.
Michael Bishop seeks the Xenomorph knowledge stored in the android's mind, and brings
Bishop back to life—but for what reason? No longer an employee of the Weyland-Yutani
Corporation, Michael tells his creation that he seeks to advance medical research for the benefit
of humanity. Yet where does he get the resources needed to advance his work, and with whom
do his new allegiances lie?

The USCSS Patna is pursued by Colonial Marines Captain Marcel Apone, commander of the Il
Conde and younger brother of Master Sergeant Alexander Apone, one of the casualties of the
doomed mission to LV-426. Also on his trail are the "Dog Catchers," commandos employed by
Weyland-Yutani.

There are many who would profit from Lance Bishop's intimate knowledge of the deadliest
creatures in the galaxy.
