ASCENSION

In 1991, British scientist Harold Tunmore and an international crew have their minds blown and lives threatened after being summoned to a gigantic mountain in the South Pacific that bizarrely appeared out of nowhere.

From the start, Harold and his colleagues have reasons to be nervous about the expedition. Their anonymous sponsors, possibly military, refuse to divulge pertinent information—including what happened to those who didn't survive a previous visit to the mountain and why one who did–Harold's lamented ex-wife–remains there in a starkly incommunicative state. But once the group begins the treacherous task of climbing the mountain in the frostbite-rendering cold, there is no turning back. The higher they climb, the weirder things get. People start acting strangely, turning on each other in sometimes violent fashion. Some of them disappear after slipping through what are revealed to be folds in time and space. (Scary tentacled creatures await them.) Harold starts having memories that aren't his. Increasingly, he enters into a volatile state of consciousness in which his personal failures—notably his long-ago neglect of his wife and adopted son—play out against psychedeliclike religious visions. The novel opens with Harold's brother, Ben, finding him in a psychiatric hospital nearly 30 years after Harold went missing and was declared dead. The story unfolds through a series of unsent letters Ben finds in Harold's room, written back in 1991 to Ben's then-teenage daughter. At its best, the book is a cross between Journey to the Center of the Earth and Heart of Darkness. But it needs a less whiny protagonist to serve its mega-reflections on the meaning of life and the future of mankind and doesn't do enough with supporting characters, especially a renowned female Russian biologist.

An entertaining SF thriller that's unable to catch up to its vision.
