What Dreams May Come by Richard Matheson

What happens to us after we die? Chris Nielsen had no idea, until an unexpected accident cut his life short, separating him from his beloved wife, Annie. Now Chris must discover the true nature of life after death.

But even Heaven is not complete without Annie, and the divided soul mates will do anything to reach each other across the boundaries between life and death. When tragedy threatens to divide them forever, Chris risks his very soul to save Annie from an eternity of despair.
