Remains of the Past - S. C. Loader - Bog

Six years after the fall of modern civilisation, a wandering survivor Maja, meets an adaptive and highly resourceful survivor, Max.
She persuades him to escort her to a known group of survivors where they can both build a future. A tentative, romantic relationship forms between them, but Maja's disinterest in a deeper relationship and her unethical choice of punishment for those men who have abused women, causes Max to reconsider his future at her side.
