Promise Me Not is the second book in Meagan Brandy's Boys of Avix series, following Payton, who fled her hometown to escape a toxic home life and left behind her senior year and the best friend who had become the love of her life — and the father of her unborn child. He tracks her down and the two begin building the family neither of them had growing up, until a car accident kills him on his way home, leaving Payton a teenage single mother facing an uncertain future alone.
Years later, Payton meets Mason Johnson, heading into his first season as starting quarterback at a Division I university. Mason wasn't looking for a ready-made family, but Payton and her son quickly become the life he doesn't want to live without. The novel is a slow-burn new adult romance built around grief, single parenthood, and learning to trust love again after devastating loss.
