Query: A powerful account of a very important set of events of WW2.

This is a historical fiction account of the developement of the atomic bomb and the USS Indianapolis (the ship that delivered one of the bombs to the Pacific Theater). The author utilized all available historical records to add as much authenticity to the story as possible, and creates a very plausible storyline. The story of survival near the end of the book is enough to make you think twice of being in the water.
