A Short Stay in Hell by Steven L. Peck

An ordinary family man, geologist, and Mormon, Soren Johansson has always believed he’ll be reunited with his loved ones after death in an eternal hereafter. Then, he dies. Soren wakes to find himself cast by a God he has never heard of into a Hell whose dimensions he can barely grasp: a vast library he can only escape from by finding the book that contains the story of his life.
