British Fantasy Award nominee 2014.
Pen’s life is all about secrets: the secret of the city’s spirits, deities and monsters her best friend Beth discovered, living just beyond the notice of modern Londoners; the secret of how she got the intricate scars that disfigure her so cruelly – and the most closely guarded secret of all: Parva, her mirror-sister, forged from her reflections in a school bathroom mirror. Pen’s reflected twin is the only girl who really understands her.
Then Parva is abducted and Pen makes a terrible argain for the means to track her down. In London-Under-Glass looks are currency, and Pen’s scars make her a rare and valuable commodity. But some in the reflected city will do anything to keep Pen from the secret of what happened to the sister who shared her face.
