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.
Sea of Tranquility by Emily St John Mandel
Yes, I loved this one!
O shit thanks for reminding me to start this one. Loved S11 and Glass Hotel.
They all tie together in some way
I read that a few months ago. Loved every page
Came straight into the comments looking for this. Her way of making you think about things that you wouldn’t think of necessarily but that also feel evidently true and part of your self is incredible. It’s such a moving book!
Such a beautiful trip through space time and imagination. I absolutely loved this book!
