Books where the destined lovers first meet each other after a long time. The author has teased their meeting for almost first half of the book, peppered with almost opportunities and thwarted efforts. Think Meg Ryan and Tom Hanks in SLEEPLESS IN SEATTLE, we know they're the lovers but they meet for the first time very late into the movie. Add books like that here, no matter the genre but the love story has to have a prominent role in the story.
