When Ellen Ripley finally returns to Earth, she learns that the planet LV-426—now called Acheron—has been colonized. But LV-426 is where Ripley and the crew of the Nostromo found the original Xenomorph—the killing machine known as the Alien.
Protected by the Colonial Marines, the colonists seek to terraform the storm-swept planet. Two such residents are Anne and Russell Jorden, seeking a fortune that eluded them on Earth. On Acheron, Anne gives birth to the colony’s first newborn. Rebecca Jorden, also known as Newt.
