Is My Best Friend's Betrayal Due to Jealousy or Another Hidden Secret?

Looking for a Cozy, Feel-Good, Healing Book Without the Usual Cliches

I've always felt pretty down. I have a habit of reading, so I'm looking for a book to help me unwind, but everything is either about face-slapping or follows the same old formula. I'm hoping well-read, widely traveled fellow readers can recommend something warm, uplifting, and healing.
