Robin Cook is the author -- and Coma is the book -- for which the term medical thriller was first used. It's a spine-chilling shocker about a crime beyond imagining and the committed young medical student who brings it to light.The surgery was routine -- the kind performed many times a day at Boston's most prestigious hospital.

Several patients, admitted to the hospital for minor surgery, never awoke. For some inexplicable reason, their brains had been destroyed.
