Meet Sage Poe—witch, programmer, and amateur detective. She thought the hardest part of summer would be helping Bone Gap adjust to its newly-revealed magical nature. Then they found the body at the cemetery gates. When a bearded stranger turns up dead outside Bone Gap Cemetery with no visible wounds but unmistakable magical residue, the official ruling is natural causes. But Sage knows better. What begins as an unofficial investigation soon uncovers a famous musician in hiding, ancient demonic contracts, and creative energy harvested like crop.

Enter Aunt Hecate—whose improving magical dementia hides a sacrifice spanning decades. Her mind wasn't clouded by age but by choice—a demonic bargain made before Sage's youngest sister was born. Now the same demon has come to collect another debt, and the connection hits closer to home than anyone suspected. Meanwhile, Sheriff Emmet Quill finds himself caught between upholding the law and helping the woman he loves investigate forces beyond mortal jurisdiction. As Bone Gap fractures between those embracing their magical reality and those fighting against it, even their relationship hangs in the balance. With magical ley lines converging beneath three cemeteries, shadowy figures captured in photographs, and melodies that hide protection spells, Sage must solve the case before more souls pay the ultimate price.
