The Rec League: Time Loops

This Rec League comes from our SBTB Patreon Discord, from user LyricLorelei:
Does anyone have any good time loop story recs? Or things with showing multiple options/versions of life choices?
Amanda : There were a bunch of great recs in the Discord, but I thought opening it up to the larger community would be even better.
We had a Rec League on Dual Timelines that may have some overlap here.
Elyse :  Yes! The Darkness Outside Us  ( A | BN | K )
It’s m/m sci-fi romance and I ugly cried
Shana : Twice in a Lifetime by Melissa Baron is basically a retelling of the Keanu Reeves movie The Lake House , but there are at a few time loops as she keeps trying to reset the past.
A | BN | K Sarah : This may be not quite what this person is after, but The Last Daughter of York ( A | BN | K ) has a time slip and the plot does circle somewhat (trying not to be spoilery).
Time slip, where characters move back and forth between time periods ( Nicola Cornick , Susanna Kearsley) aren’t quite the same thing as time loops.
This is How You Lose the Time War  ( A | BN | K | G | AB )
A Knight in Shining Armor ( A | BN | K | G | AB ) is probably one of the most famous.
See You Yesterday by Rachel Lynn Solomon ( A | BN | K | AB ) – that has a character stuck in a one-day repeat
Sneezy : Through a Dark Glass by Barb Hendee ( A | BN | K | G | AB )
Elyse : Outlander , obvs. ( A | K | G | AB | Au )
