It's probably forbidden to nominate your own novels but Lucifer's Dragon has high levels of implicit nanotechnology, Drexler boxes - a nanetic defence wall, nanotechnology-based genetic manipulation...
reMix, the follow-up (not out till just before Christmas) is almost entirely nanotech-based. And the first book neoAddix has nanotechnology as something disliked by fundamental Christianity and Islam as interfering with the work of God...
Okay, that's it. Also not sure if books have to be available in US. neoA
and LD aren't, though they are available in Canada.
