A haunted painting… A phantom’s game… And a nightmare that bleeds into reality.

Sadie Stewart is ready to dazzle Chicago’s art world with her gallery’s Halloween show, a night meant for art and celebration. But when a mysterious painting appears—depicting Sadie herself in a desolate landscape of thorns and blood—her triumph turns chilling.

Beneath the canvas lies a bloodstained scarf and a warning: Obey the phantom’s rules, or more will die.

With only her intuition, her loyal dog Solomon, and the steady support of her best friend Daniel, Sadie follows a sinister trail of clues across Chicago, from haunted mansions to glittering masquerade halls.

Each “treat” hides a trick, each riddle another snare in the phantom’s deadly game.
