Reverse age-gap romances are a favorite of mine, especially when the heroine falls in love with a younger hero. But I have a soft spot for a unique twist: when a young heroine ends up falling for her ex-boyfriend’s dad. The forbidden nature of this trope adds an extra layer of intrigue and tension. How will the father reveal his feelings to his son? What impact will this love have on their relationship?
This niche trope offers authors plenty of room to get creative, and I’ve compiled a list of 18 books that highlight the ex-boyfriend’s dad forbidden romance trope. Let’s dive into these steamy, taboo love stories!
