I found the two short stories by Bradbury and Heinlein very interesting.
A sound of Thunder, by Ray Bradbury captured my interest as I was following along trying to learn how the story unfolded and ultimately ended. The story reminds me of a current show on television named ‘Westworld”on HBO as the characters in that script were also going on a time travel trip. The fact that any minor changes or differences can have a huge consequences and alter existing facts of the real world I find interesting.
All You Zombies, by Robert Heinlein also captivated my attention. I was immediately drawn once the reader became aware of the situation in the hospital room once the delivery was over. As a male, I found the events of questioning someone’s identity frightening, and consulting them while under medication and choosing to reassign their sexual organs… greatly disturbing.
