You know what's funny? My novella sub+Human that's coming out in an anthology this month is considered "Age Gap" because there's about a 10 year difference between the human (older) and vampire (younger). My series, The Bloodline Chronicles, has these characters: 24 year old FMC 🧙🏼‍♀️ 570 year old FMC 🧛🏻‍♀️ 2500+ year old MMC 🧛🏻‍♂️ But it is not considered "Age Gap" romance. XD
