What was the light that mazed every mind's eye? What has brought a flying mountain top home from the stars, and sent investigators into the orbital habitats floating above Earth? How is this connected to a "living fossil" fungus--or to a dead madman--or to the fate of the planet? Whoever discovers the answers to these questions--FIRST!--will decide the ultimate fate of the Earth--and all humanity! An imaginative tour de force.
IMHO Mr. Hendrix has used his many degrees to concoct a buzzword-laden novel from heck. If the idea of reading a sentence like "...the upshot of of crypto-behaviourist ideas ... at least in academic circles, was a generalized denial of the actuality of individual consciousness" every few pages doesn't turn you on, then stay away.
There are times when ideas drown plot, characters and so on. A brave attempt at charting transcendence though I rarely care for an alien deus ex machina.
