MC is a long-haul truck driver. He gets divorced. his wife was either pregnant at the time or the baby was an infant. He promised ex he would not interfere with her or the child's life. When he comes home from a run he reads in the paper that the girl (grown up now) is very ill and needs kidney transplant but they are having a hard time finding donor. He he goes to hospital an is tested and is a match. I can remember a few more details if this is not enough. It was a medium length story
