Manx- Window Freeze

  When she stepped through the batwing doors, the boy was at the rear door, his face up against the glass of the window set into it. He grinned to show his mouthful of delicate hooks, those fine rows of curving bones. His breath spread feathers of silvery frost across the pane.
...

  She heard a crunch behind her, whirled, and saw that the little boy had slammed his forehead into the window. A spiderweb of shattered glass filled the pane. The boy himself seemed uninjured.

  Back in the foyer, she heard Manx force the front door open, heard it catch against the chain.

  The child pulled his head back, then snapped it forward, and his forehead hit the window with another hard crunch. Splinters of glass fell. The boy laughed.
