The I-phone disguised space and time machine, of (so far) unknown origin. What it does ...
We get a follow-on, or rework of "Rescued" with more clues added, with a different perspective (view-point) from the original story. Except: is it different? While it repeats the theme, it also puts in a lot more famework around what happens, and finally gets around to retelling the original as seen 'through a crack behind the door'.
I am being cryptic, because I don't want to spoil anything. This is as good a sf yarn as I've seen on SOL. Read the original story first. If you can handle that, you will really like this, I predict.
