The Seven Story Mountain by Thomas Merton, an autobiography outlining how he went from an unsettled childhood in which he lost his mom at a young age, traveled with his dad who was a painter (fine arts), and was put in various boarding schools and left with various relatives. He had a somewhat debauched career as a student at Cambridge in England and later at Columbia U. in NYC. I'm not a Roman Catholic, though I grew up with many Catholic kids in the Chicago area, so have a fairly developed sense of Catholic culture, by immersion. I like any account that describes the evolution of development and thought leading to a calling in life, in Merton's case, as a Trappist monk. I kind of compare and contrast this with Oliver Sacks autobiography On The Move, another similar account, though Sacks was an extremely different person.
