Blindsight is wonderful. A bit difficult to follow at a time due to the 'unique' writing style. In the same novel it tackles uploading consciousness, vampires, artificial intelligence, aliens, psychology (heavily) and a few more things.

I've yet to find a better description of what would be an actual alien lifeform. Even if it is biased a bit on marine biology given the author's qualifications, the oceans are host to the most 'alien' environments we are aware of that still contain life.

I still can't wrap my head on the concept of the Icarus Array though.

Anyway, for the uninitiated: https://rifters.com/real/Blindsight.htm
