Interesting ideas, wandering, shaky execution, and a dippy, unlikeable protagonist. Great opening, good teaser ending, some marvelous setpieces. I'd read the next.... but I don't think it ever appeared....
Hmm. In his review, Paul Di Filippo says K-Machines concludes a duology with Godplayers -- if so, Broderick is leaving a mop-head of loose ends... As with Godplayers, I wanted to like this book more than I could. Worth reading, I guess, but YMMV.
