To be talented in magic is a rare gift, rarer still in a pegasus. For Featherfall, each spell comes at a cost: one of her precious feathers.
Part of Canterlot's elite Magical Crimes Unit, Featherfall struggles to solve the disappearances of two well-liked mares and the brutal murder of a renowned candle-maker, burned alive in his own shop. But, as the facts of the case emerge, Featherfall finds her own family implicated for the grisly crime and unearths hints of a far greater horror.
