From author and Billboard Music Award-winning music producer Mark Maxwell comes a fresh take on the literary thriller genre, for fans of Tana French and David Mitchell, about a young woman's search for a missing songwriter entangled in the occult.

The night Relic Castano disappeared, he left three things behind: an unfinished record with the world’s most iconic pop band; an Irish castle entombed with secrets; and a tell-all journal…shrouded in the occult.

Eight months later, Ellen Row, a twenty-eight-year-old music manager from Los Angeles, is still struggling to accept the loss of her once-budding client and best friend. In a case with no leads and no suspects, Ellen is cruelly reminded of her brother, who vanished over a decade earlier. But when Ellen receives an anonymous tip on Relic’s case, encrypted in an astrological riddle, she realizes there’s another dimension to the story—one she’s terrified to unfold.

Now bound for Ireland, Ellen Row, and a wonderfully witchy new friend, must unearth Relic Castano’s secrets before they come unraveled by their own. They have the riddles of a faceless stalker, they have the stars of an ever-shifting zodiac, but what they don’t have is time. As pages from Relic’s journal begin to emerge, every step toward the truth becomes a step toward disaster.
