After high school graduation, Mia Peters faces a summer full of painful goodbyes. Songwriting is her only solace. Everyone she knows is moving on, including Britt, her biggest supporter … and kind-of-sort-of girlfriend. Britt keeps pushing Mia to go bigger and do better than their small town, but Mia can’t imagine a life beyond Sunset Cove. Besides, she refuses to follow in the footsteps of her late mother–country music star Tori Rose–who abandoned her family to pursue her dream, leaving Mia and her two grandmothers alone. Desperate for a sign of what might lie ahead, Mia finds the opposite–a mysterious letter from the past, addressed to her in her mother’s handwriting. It turns out to be the first of many. One by one they lead Mia on a wild scavenger hunt through a Sunset Cove she never knew, buried under the memorializing that has frozen her mother in time. Each new discovery brings Mia closer to the real Tori Rose, but with the clock ticking on Britt’s departure, Mia knows she is running out of time. With the summer winding down, Mia must decide if she is ready to face the present, confront her feelings, and forge the destiny she truly wants.
