The Exodus Towers features all the high-octane action and richly imagined characters of The Darwin Elevator—but the stakes have never been higher.   

The sudden appearance of a second space elevator in Brazil only deepens the mystery about the aliens who provided it: the Builders. Scavenger crew captain Skyler Luiken and brilliant scientist Dr. Tania Sharma have formed a colony around the new Elevator’s base, utilizing mobile towers to protect humans from the Builders’ plague. But they are soon under attack from a roving band of plague-immune soldiers. Cut off from the colony, Skyler must wage a one-man war against the new threat as well as murderous subhumans and thugs from Darwin—all while trying to solve the puzzle of the Builders’ master plan . . . before it’s too late for the last vestiges of humanity.
