Angle of Repose by Wallace Stegner

This novel follows the story of a retired historian, wheelchair-bound due to a degenerative disease, as he explores the lives of his pioneering grandparents in the late 19th and early 20th century American West. Through letters, he pieces together their struggles, triumphs, and the impact of their relationship on their surroundings. The historian parallels his own life and failed marriage with that of his grandparents, leading to a deep exploration of the concepts of stability, perseverance, and the "angle of repose."
