Ok this might be a little bit too specific, so I don't know if there's going to be a book like this; I tried searching by myself but I found nothing. A long time ago I watched a show where the main character travels to the past and ends up meeting his parents when they were teenagers, and realizes a lot of things he didn't know about them or their families. Recently another show came out with a very similar trope and I loved it too.
I was wondering if there was any book that has this aspect of time traveling + meeting family, either from the past or in the future, that someone can recommend me. It doesn't need to be exactly like that, just something similar
