An uncorrected proof copy in green wrappers. Winner of the Hugo Award for best novel in1989, Cyteen is the sequel to DOWN BELOW STATION which won in 1982. An indentation of about 1/4" on the back cover that affects the first 4 pages, but that does not cut, and a bump at the top front edge at the spine that has caused a small tear are the only flaws on this otherwise unread copy..
