Synopsis: From the front flap of the Tor first edition: Sector General. It's the massive hospital space station - 384 levels, with a staff of thousands - on the Galactic Rim, where human and alien medicine meet. It's also the setting for some of the most entertaining novels of modern SF, James White's Sector General series, which began three decades ago with Hospital Station. Now, in Final Diagnosis, the multispecies Sector General medical staff rides (so to speak) again. It's always been an article of faith at Sector General that infections can't pass from one alien species to another. But in a season of anomalies, it looks like they may have their first interstellar virus on their hands, their tentacles, their cilia... With its intriguing puzzles and ingenious solutions, action and adventure, and endlessly fascinating aliens (including the bipedal Terran variety), all told with White's characteristic easy charm, Final Diagnosis is a science fiction treat.
