Chaga

On the trail of the mystery of Saturn's disappearing moons, network journalist Gaby McAslan finds herself in Africa researching the Kilimanjaro Event: a meteor-strike in Kenya which caused the stunning 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. But when Gaby finds the first man to survive the Chaga's changes, she realizes it has its own plans for humankind...

Against the backdrop of Mount Kilimanjaro, McDonald weaves a staggering tale of keen human observation and speculation, as the Kilimanjaro Event changes the course of the human race by exposure to something beyond its imagination.

Note: Chaga was published in the UK under the title Evolution's Shore.

Both form and substance blend fortuitously in a work that features strong characters, a suspenseful story, and a profound message of hope and transformation. A priority purchase for SF collections." –Library Journal

"One of the finest writers of his generation, who chooses to write science fiction because that is how he can best illuminate the world." –New Statesman
