Williams, Liz -- Banner of Souls

Far-far future Solar System, after eons of biological and nanotechnological engineering. The penis is obsolete. Earth is flooded, hot, moldy, and a backwater satrapy of the Martian Matriarchs. That old nanotech crap has been obsoleted by haunt-tech (a gift of the alien Kami), which seems to work via actual ghosts. A girl with mysterious powers is hunted by one warrior, guarded by another. The setting isn't Mieville but it's the next best thing, and the plot holds together pretty well. Albeit with the requisite Mysterious Resolution (which is merely adequate).
