Welcome to sffworld, kantor.

This sounds more like sf to me so I moved it here. Apart from that - the Book Club was not the place to post it either. Just saying. ;)

For your question: I can't help you, don't know that book. Hope you find answers here. :)

Sounds (with some differences) like David Brin's The Practice effect.
