Kiss of Venom - Jennifer Estep
Owen did a nice thing in this novella, but he is actually right there's not a thing that can turn back time and make Gin forgive him, by his reactions and the way their relationship simply desapeared after she killed Sabine.

But it was actually nice seeing things from Owen POV and the way he's strugling to find peace and deal with his emotions. It was also perfect seeing him fighting for Gin and saving her, not that she needed, but Owen does know how to make a woman feel special.
