Query: I've read it three times. A great book.

A planet in terminal orbit, one side searing hot, the other frozen. On the fringe between the two stands Nightside city. In this erie cyberpunk tale, a detective rubs elbows with all sorts of low-lifes in a quest to determine whether Nightside city will soon see the light of day...and who's behind it. Masterfully presented with wonderful descriptions, great dialog, and visionary descriptions of future technology. Evans makes it all come alive.
