I read that ages ago. Back in high school, in fact (I’m 46). I don’t remember it except the chapter where time is a flock of birds that you have to try to catch to stay youthful. The children can catch them but always let them go and the adults can never catch them.
I remember how in The Matrix movies, humans blocked out the sun to stop the computers from taking over. Looks like we’re going to ask them whether or not that’s a good plan first in our timeline.
I remember it was in the new books section of the school library and I was attracted to it immediately and spent the day reading it instead of paying attention in my classes. I need to read it again. Thanks for bringing it up!
