Jordan, an 18-year-old athlete, finds his joints weak and begins to stumble unaccountably. The local doctor who has known him all his life sends him to the Mayo clinic where a diagnosis of Lou Gherig’s disease is confirmed. His mother, three brothers, sister, and brother-in-law (an Episcopalian priest) accommodate to his illness, with its promise of early death, in various ways.

The family is supportive, though the youngest brother goes through weeks of denial that look like rejection before he allows himself to feel the emotional impact. Jordan’s adored girlfriend can’t rise to the challenge of loving a boy with no future, and distances herself, but leaves it up to him to acknowledge and effect a separation that leaves her free to pursue other relationships, and him to burrow deeper into the loving family that sustains him in his final months. He takes one last trip to the Colorado mountains with his younger brother where they meet an old mountaineer who senses immediately what might be happening and becomes for Jordan the type and figure of the wise old man.

Here as in other stories of this kind, time seems to conflate for the young person facing death; maturity comes in sudden leaps, and a certain calm descends before the end. One of Jordan’s final acts is to serve as godfather at the baptism of his sister’s baby, his namesake. The act and the letter he writes the child gives him a sense of leaving behind a legacy that matters.
