One Small Part of Heaven tells parallel stories, one in the natural world and one in the spiritual. A man is hit by a car and killed. He ends up in the spiritual world. About the same time, over a thousand miles away, a young housewife is in a traffic accident and is killed, and she too ends up in the spiritual world. They're almost immediately together, because they are perfect for each other and because they are meant to be together. They do not interact with the natural world nor seek closure with it. They go to one small part of heaven and are very happy there. Meanwhile, their spouses in the natural world meet each other and are married, and are almost happy together, in spite of all the trials and tribulations on earth, until they too enter the spiritual world and go to their small part of heaven.
