If you like Banks, MacLeod, Mieville, Vinge, McAuley, Stephenson and Gibson, you should read this. As good or better as any of their best. It's hard sf, it's literary - it features rounded sympathetic characters, the vast scale of space opera, suspense, intense sex, lost loves, ghost programs, psycho killers, contract assassins, intergalactic carnivals, aliens, virtual worlds, a singularity, human-machine blendings, science funding battles, subtle pop references, condensed visual imagery, 3 different narrative streams...and a universe of "more...and more after that." Wow.
