Kerrigan Argon - half-human, half-fairy - joined the Society against the wishes of almost everyone. Now she needs to train with her dragon for a year. But first she needs to visit the dark prince of the fairies, Fordham Olivier, in his home, the House of Shadows. Only slavery and death await the half-fairies in their halls. But something is wrong with their world. The spell has held for a thousand years, but is weakening. Cracks appeared in the wall surrounding them. And Kerrigan can save them or destroy them.
