From the #1 New York Times bestselling author of This Is Where It Ends comes an intense story of loss and the quest for truth Corey and her best friend, Kyra, are inseparable.

Corey is the only person who understands Kyra's high-highs and low-lows. So when Corey's family moves away from their Alaskan town, she makes Kyra promise to stay strong during the long, dark winters and wait for her return. Except Kyra doesn't. Two days before Corey is to visit, Kyra is found floating underneath the ice.

While everyone in Lost Creek deems Kyra's death a suicide, Corey knows something is wrong. With every hour, her suspicion grows. The town is keeping secrets-chilling secrets. But piecing together the truth about what happened to Kyra may prove as difficult as lighting the sky in an Alaskan winter.
