Given the short nature of this story, I think I will just give it an overall review, as opposed to trying to split it into good and bad sections. My main complaint has to do with copy-editing; there are quite a few punctuation issues. Strangely enough, the lack of necessary commas, etc., seems to be the only major issue that I could find.
The story begins against a snowy backdrop in a grove of evergreens. We are presented with three characters and right from the beginning, we know that these characters are acquainted with a world that isn't Earth - although we don't know much more about their past than that. The characters then discover a body, and we are led to believe that while it may not be a part of their yet-unclear directive, they find it important to somehow resolve the situation. (Sorry for any awkwardness - I'm trying very hard not to give too much away.)
Right from the beginning, I was impressed by several things. Owens has a good understanding of effective POV and the proper amount of description - we are treated to some nice imagery and the feel of the characters, without a running list of their every characteristic.
As the story progressed, I also enjoyed his sense of flow and pacing. The story quickly leads its reader from a sense of general curiosity to mystery, and later to moments of terror. The storytelling is apt, with a good mixture of show and tell, and by the end, I wanted to read more about these interesting "Timewasters."
