Athanasios “Athan” Bakirtzis hasn’t had an easy life. Orphaned by a fire at a young age, he’s had to rely on his charm, his under-the-table job as an art handler, and the generosity of family friends to care for his ailing Yiayia, his grandmother.

But Athan also has a secret: a hereditary power that allows him to rewind the reflection in any mirror, peering into its recent past. Superstitious Yiayia calls the family ability a curse, and has long warned him never to use it. For Athan, who’s survived this long by keeping to the realm of the real, this is a perfectly agreeable arrangement.

Until the night of the party. After being invited to a penthouse soiree for New York’s art elite, Athan breaks his grandmother’s rule during a trip to the bathroom, turning back his reflection for just a moment. Then he hears a slam against the bathroom door, followed by a scream. Athan peers outside, only to be pushed back in by a boy his age. The boy gravely tells him not to open the door, then closes Athan in.

Before Athan can process what’s happening, more screams follow, and the party descends into chaos. When he finally emerges, he discovers a massacre where the victims appear to have arranged themselves into a disturbingly elegant sculpture—and Athan’s mysterious savior is nowhere to be found.

Something evil is compelling people to destructive acts, a presence that’s been hiding behind Athan’s reflection his whole life, watching and biding its time. Soon, he’s swept up in a supernatural conspiracy that spans New York, of occult high societies and deadly eldritch designs. If beauty really is in the eye of the beholder, what can it do to us once it’s inside?
