Vasquez
(Book)

Even before the doomed mission to Hadley's Hope, Jenette Vasquez had to fight to survive. Born to an immigrant family with a long military tradition she looked up to the stars, but life pulled her back down to Earth. The Colonial Marines proved to be Vasquez's way out, but she was forced her to give up her twin children. Raised by Jenette's sister Roseanna, those children--Leticia and Ramón--have been forced to discover their own ways to survive. Their paths converge on an unnamed world, which some see as a potential utopia, while others would use it for highly secretive research. Regardless of what humans might have planned for it, however, Xenomorphs will turn the planet into a living hell.
