Once Upon a Time the Beryl crystal maintained equilibrium in the mythical kingdom of Faerie, which resides alongside our own mortal world. When the crystal was stolen, the land of Faerie began to slowly perish.
When researcher Sophia Rose comes across an ancient crystal in Cambridge's Fitzwilliam Museum it represents an unwelcome intrusion of mythical knowledge into her carefully ordinary life. Though descended from the magical and mythical Fair Folk, she is determined to remain untouched by her family's legacy. She hides the crystal, but Sophia finds it impossible to hold the world of Faerie at bay any longer.
