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.
I loved ‘An Idiots Guide to Time Travel in the 30th Century’. It gave me enough information to get here, but I forgot to bring a copy with me.
Sadly I’m stuck here now and it isn’t yet written.
😂
Did you try to attend Stephen Hawking’s time travel party? Too bad no oneto made it 🥲
