Here's the key words you need to consider:
The White Plague by Frank Herbert
The X Files
"We Can Remember It for You Wholesale" by Philip K. Dick
Shade's Children by Garth Nix
Think these are spoilers or teasers? Ideally, they should operate as both. :)
This is the book: Nexus by Ramez Naam. It's brilliant.
You want to read Nexus. Really you do. Trust me on this. It's about today and about tomorrow and about things you hate and about things you love. About potential and people and who we all are... and who we could be.
Have some Nexus, do. You know you want to, you want it so very much for all sorts of reasons. Because Homo sapiens is that way.
-- Thanks to NYRSF for the subject line, which I might pinch in future for other book recs.
