This was the first Asimov book I ever read. It sure did hook me! I remember feeling I was right there with the characters, speeding through the bloodstream, exhilerated and frightened and fascinated.

A very good medical/science thriller. Set in the future the book tells the story of a journey through the body. The author combines elements of science fiction, medicine and mystery to tell a great tale of how medical and scientific personnel combine to try and save a member of their own by using new and unorthodox medicine.

An atomic submarine is reduced to a size smaller than a single red blood cell, and is injected into a dying man. The crew struggles to save the man's life by locating and destroying a blood clot before the submarine returns to its original size.
This story was based on a screenplay by Harry Kleiner that was made into a movie in the 1960's.
