Wanting a dark past that catches up with someone who got away, and now needs to protect the peace/happiness they’ve carved out.

I'm curious about novels or series where the main character has ran from/moved on from a darker past, but now it is catching up with them. Preferably in a healing from trauma type of way that has a hopeful perspective of overcoming it in the end. Or, Someone who got away, had a taste of a better life, but now has to face the darkness again once and for all to keep what they've gained.

In terms of stakes, I like when the stakes are more personal than global. Like their life may be ruined, but the world will keep spinning if all fails. I like when I can get very invested in the characters and their relationships rather than a high stakes plot.
