What happens when your soul is bound to another before you were ever born? Lonny and Roo have been best friends since they met in high school in 1975 at the age of fourteen. Same last name, same birthdate, they were attached at the hip; rarely was one seen without the other. Together they navigate through their emotional high school years, but nothing prepares the naive teenagers for the real world ahead of them. Now on the cusp of their fiftieth birthday, Lonny finds Roo broke and alone and convinces her to leave with him on a cross country road trip from New York to Las Vegas, hoping to set her on a new path in life. Told exclusively by Roo, follow the friends back and forth through their unique relationship — experience the loss of innocence, career and life choices that separate and unite them, and unspeakable events that nearly destroy them. It’s a love only they understand, as well as the unbreakable bond that forever ties them together. Is it possible they are only capable of loving each other?
