Alien: Out of the Shadows
As a child, Chris Hooper dreamed of monsters. But in deep space, he found only darkness and isolation. Then on planet LV178, he and his fellow miners discovered a storm-scoured, sand-blasted hell - and trimonite, the hardest material known to man.
When a shuttle crashed into the mining ship Marion, the miners learn that there was more than trimonite deep in the caverns. There was evil, hibernating - and waiting for suitable prey.
Hoop and his associates uncover a nest of Xenomorphs, and hell takes on new meaning. Quickly they discover that their only hope lies with the unlikeliest of saviors...
Ellen Ripley, the last human survivor of the salvage ship Nostromo.
Sea of sorrows
As a deputy commissioner for the ICC, Alan Decker’s job is to make sure the settlements on LV178 follow all the rules, keeping the colonists safe. But the planet known as New Galveston holds secrets, lurking deep beneath the toxic sands dubbed the Sea of Sorrows.
The Weyland-Yutani Corporation has secrets of its own, as Decker discovers when he is forced to join a team of mercenaries sent to investigate an ancient excavation. Somewhere in that long-forgotten dig lies the thing the company wants most in the universe—a living Xenomorph.
Decker doesn’t understand why they need him, until his own past comes back to haunt him. Centuries ago, his ancestor fought the Aliens, launching a bloody vendetta that was never satisfied. That was when the creatures swore revenge on the Destroyer… Ellen Ripley .
