Bridget’s most important job has always been protecting her younger sister, Dahlia. But as adults, Dahlia pushes her away, determined to live her own life.

Then, Dahlia vanishes. When her car is found submerged in the river, the authorities tell Bridget to prepare for the worst. Nine months later, everyone has given up hope. Everyone except Bridget.

When a former classmate of Dahlia’s comes forward with a new lead, Bridget takes matters into her own hands. She ignores the dismissive detective’s warnings and launches her own amateur investigation. The search leads Bridget to something far more sinister than a typical missing persons case—a carefully-guarded plot tied to powerful, age-old magic.

To uncover the truth of what happened to her sister, Bridget must confront this dangerous world, even if it means putting her own life on the line.
