James White captures all the breathtaking excitement of the perils and rewards of the future's medical frontiers in this gripping book. Sector General: a massive deep-space hospital station on the Galactic Rim, where human and alien medicine meet. Its 384 levels and thousands of staff members are supposedly able to meet the needs of any conceivable alien patient – though that capacity is always being strained as more (and stranger) alien races turn up to join the galactic community. Sentient viruses, interspecies romances, undreamed-of institutional catering problems – it all lands on Sector General's doorstep.
