For three teenagers, dark mystery has always lurked at the corner of the eyes and the edge of sleep. Beautiful Morgan D'Amici wakes in her trailerpark home with dirt and blood under her fingernails. Paintings come alive under Ondine Mason's violet-eyed gaze. Haunted runaway Nix Saint-Michael sees halos of light around people about to die.

At a secret summer rave in the woods, the three teenagers learn of their true, changeling nature and their uncertain, intertwined destinies. Riveting, unflinching, beautiful, Betwixt shows a magic as complex and challenging as any ordinary reality.
