Blankets by Craig Thompson

An autobiographical comic, intertwins the stories of his relationships with his younger brother, Phil (with whom he had to share blankets as a child), and with his first girlfriend, Raina (with whom he also shared a blanket). Raised by strict Catholic parents, Thompson struggles with his own faith, attracted to the message but repelled by the Church, and his black-and-white art makes use of Christian imagery.

This is one of the first graphic novels that I've ever read. It is over 500 pages which at first is rather daunting but since it is illustrated comic style it flows quickly. His is not a particularly happy life, full of many disappointments but it is interesting to see how his life evolves.
