Seventeen-year-old Parker Frost has never taken the road less traveled. Valedictorian and quintessential good girl, she’s about to graduate high school without ever having kissed her crush or broken the rules. So when fate drops a clue in her lap—one that might be the key to unraveling a town mystery—she decides to take a chance.

Julianna Farnetti and Shane Cruz are remembered as the golden couple of Summit Lakes High—perfect in every way, meant to be together forever. But Julianna’s journal tells a different story—one of doubts about Shane and a forbidden romance with an older, artistic guy. These are the secrets that were swept away with her the night that Shane’s jeep plunged into an icy river, leaving behind a grieving town and no bodies to bury.

Reading Julianna’s journal gives Parker the courage to start to really live—and it also gives her reasons to question what really happened the night of the accident. Armed with clues from the past, Parker enlists the help of her best friend, Kat, and Trevor, her longtime crush, to track down some leads. The mystery ends up taking Parker places that she never could have imagined. And she soon finds that taking the road less traveled makes all the difference.
