On the trail of the mystery of Saturn's disappearing moons, network journalist Gaby McAslan find herself in Aftrica researching the Kilimanjaro Event: a meteor which landed in Kenya causing the striking African landscape to give way to something equally beautiful - and indescribably alien. Dubbed the Chaga, the alien flora destroys all man-made materials, and moulds human flesh, bone and spirit to its own designs. And when Gaby McAsland finds the first man to survive the Chaga's changes, she realizes it has its own plans for humankind.
