11/22/63 (2011)- This was one of the best time travel stories I have read. I man goes back in time to save President John F Kennedy. I won’t say anything beyond that, except it handles time travel in a reasonable manner including reverberations, and it is interesting to take the trip back including the event the story is centered on. Recommended.You might want to take a look at 11/22/63 by King. It involves time travel.
I also discovered there was a mini-series made in 2016. I’ll have to check it out!
