Fun twist on time travel, but also I think this might have worked better as a novella in some places, a play in others, a few short stories, an X-Files episode or something like that, etc. I don’t remember why I picked this up, used (in retired-library-book plastic sheathing even) or when. It’s been on my “to read” pile for a year or so. I’m probably going to drop my copy in a little free library rather than keep it.
