I'm still feeling the aftershocks of this novel. This is a book dense with ideas. It's as if someone took Michael Crichton's silly book Sphere and made a really interesting and intelligent piece of speculative fiction within the same thematic territory: what if we encountered a truly alien species? Not an inane Hollywood product of our own anthropomorphic conceits, but something that skirted the boundary of our understanding?
I will take another look at this story before long; there is no way to absorb it in full with just one reading. If you read this story and you really enjoy the experience, consider the fact that this author does his work for very little financial return, consider your karmic debt, and go to his website and make a donation to his Niblet Memorial Kibble Fund, linked here:
