Thirteen Steps is a prettily written story about loss and and grief.
The story is written in a series of "steps", like a "How To" list for succumbing to grief. Things start off on a fairly upbeat note, as the main character sets out to bring his wife back from the Underworld, and slowly, bit by bit, the journey wears on him, until he doesn't remember who he is, or what he's looking for. By the end, he realizes what he's inadvertently done, but by then it's too late.
Like I said, it's a very pretty story, but the first twelve steps are more scenery description than plot, so when the ending hits you, it takes a moment for the reality of the situation to sink in. It just felt a bit too abrupt, to me.
It made me think a lot of What Dreams May Come
