The Turtles of Tasman by Jack London — Read

Noted for his daring and success as a surgeon, through the days and weeks that followed Linday exceeded himself in daring and success. Never, because of the frightful mangling and breakage, and because of the long delay, had he encountered so terrible a case. But he had never had a healthier specimen of human wreck to work upon. Even then he would have failed, had it not been for the patient's catlike vitality and almost uncanny physical and mental grip on life.

There were days of high temperature and delirium; days of heart-sinking when Strang's pulse was barely perceptible; days when he lay conscious, eyes weary and drawn, the sweat of pain on his face. Linday was indefatigable, cruelly efficient, audacious and fortunate, daring hazard after hazard and winning. He was not content to make the man live. He devoted himself to the intricate and perilous problem of making him whole and strong again.
