I'm looking for a short story I read sometime in the mid-2000s. It was one of the "related readings" to one of the stories that I read when I was in middle school, and I'm almost sure that it had been from "A Wrinkle In Time and Related Readings" as published by Littell though I could be wrong.
The story was split into three parts. First part was when the aliens colonized the Earth and there was a scene of some school children were being taken away including the main character. Second part was set 100 years into the future where the same boy was in NY Times Square selling things at a festival for the aliens. Third part was set 1000 years into the future, where the boy was at some new alien colony in some other star system and the Earth was now uninhabitable to humans.
I don't remember the title or possible author, and I'd really appreciate it if someone knew.
