Concrete Cal

A group of adventurers searching for a cure for comatose children find themselves trapped in a sequence of virtual worlds, the only opponents of a conspiracy of the rich to live forever in a dream. Now, they are forced to make an uneasy alliance with their only surviving former enemy against his treacherous sidekick Johnny Wulgaru, a serial killer with a chance to play God forever. Few science fiction sagas have achieved the level of critical acclaim - and best-selling popularity - as Tad Williams's Otherland novels.

Mountain of Black Glass is the third volume of Tad Williams's highly acclaimed four-book series, Otherland. A truly unique reading experience combining elements of science fiction, fantasy, and techno-thriller, it is a rich epic tale in which virtual reality could prove the key to a whole new universe of possibilities for the entire human race - or become the exclusive domain of the rich and the ruthless as they seek a technological pathway to immortality.

Surrounded by secrecy, it is home to the wildest dreams and darkest nightmares. Incredible amounts of money have been lavished on it. The best minds of two generations have labored to build it. And somehow, bit by bit, it is claiming the Earth's most valuable resource - its children.
