Remember Pompeii by Kika Emers
She hasn't managed to come to that age in 200 lifetimes, but what no one else knows, is that that is on purpose. She doesn't want to lose what she has and doesn't want anything to change.
This is the lifetime when it all changes. She is being blackmailed and is left with little to no choice.
I like the premise of the story, but I had time to get into it. Kali is a very hard person to like and root for.
