My pick would have to be the A Whole Nother Story trilogy, in which (spoiler warning) you can only travel back in time. But because time is in a loop of sorts, if you go before the beginning of time, you will be at the end of time. From there you can go back to any time you want to. And time paradoxes cannot be produced. Plus, your memories from the previous timeline exist as well as the memories from the new one.
Vintage 1954 by Antoine Laurain, it’s about a group of people in Paris who drink a bottle of wine from 1954 and wake up in that year the next morning. There’s also some UFO stuff that happens that is very interesting.
It’s a very wholesome, whimsical book that fans of Midnight in Paris will like
