In this follow up chapter to Alien: Covenant, an astronaut-detective connects the dots of what went on in David's lab on Paradise. Tracing the evolution of the synthetic human's experiments with hybridization, the astronaut goes further inside the biology of the Xenomorph than any Weyland-Yutani employee before him. This last official release in the Alien franchise to date uncovers step by step where the Alien species originated.
