Surrounded by wolves in the dead of night, fourteen-year-old Katella Stone was saved by a mysterious boy with a sword.

But there aren’t any wolves on the island of Besna, and people don’t really use swords anymore.

She’s tempted to think it was just a dream, but she hasn’t had one of those in years, and when her younger brother goes missing, she’s forced to confront her impossible fears.

The unseasonably thick mist that descends every evening hides labyrinths and phantoms like the wolves from before, and the power to seal them rests in something familiar: the traditional shell beads she’s crafted since childhood.

Can she master them in time, or as phantoms increase and the mist grows thicker, will everything she knows fade forever to white?
