For me, the main appeal of a reunion romance is the prospect of getting a second chance at love. Have you ever wondered “if only …?” or “I wish I had known then what I know now”? Time and experience seasons us, and the reunion romance offers characters the opportunity to right past wrongs.
As an author, writing a reunion romance can be fun (I get to start off with the passion and emotion), but it can also be challenging as the lead characters already know each other; there’s no “getting to know you” period, for the hero and heroine already share a history. I, then, have to inform the reader about the characters’ pasts, weave their time together “off stage” into the central story. In the end, the effort is worthwhile.
