Ask HN: Need assistance from the Hive Mind

oh great Hacker News Hive Mind, not long ago (in cosmic terms anyway, probably like 4 years ago) there was a link to a short story about

  * young girl on Earth who accepts an invitation to leave the planet shortly before its doom

  * girl joins the consciousness that saved her and is basically uploaded into a cosmic computer of sorts

  * they can go active or dormant, allowing them to experience the universe in realtime or timelapse along with the billions of other saved minds (earthly and non-earthly)

  * something starts gobbling up the distributed nodes that the saved minds occupy

  * just before the end of the universe, the girl and her companion get abducted by this unknown thing that turns out to be <spoiler removed>

Something happened recently that triggered a memory of it and I wanted to track it down. I have googled and googled and googled, but I'm not finding it, so I am finally resorting to this.

Can anyone point me in the right direction?!

You're the best.
