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.
Currently working on “Wrong Time, Wrong Place” by Gillian McAllister. It’s a relatively newer release, so far it’s okay. The FMC is stuck in a reverse timeline after witnessing her 18 yr son mortally stab a stranger and go to jail. Now it’s up to her to uncover the motives behind her son’s actions and save stranger from murder.
