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.
The Shining Girls by Lauren Beukes.
A drifter in the the 30’s drunkenly stumbles into an evil, sentient house that uses him to murder extraordinary women over the next 100 years or so and the protagonist - a victim who survives - discoveres she was attacked by a time travelling serial killer.
I really enjoyed that book!
