Reason has lived fifteen years in the Australian outback with her mother, Serafina. They're on the run from Reason's grandmother, Esmeralda, who believes in magic and practices horrifying dark rituals. But when Serafina suffers a mental breakdown, Reason is sent to the one place she fears most—Esmeralda's home in Sydney.

Nothing about the house or Esmeralda is what Reason expected. For the first time she finds herself questioning her mother's teachings. Then, when she walks through Esmeralda's back door in Sydney and finds herself on a New York City street, Reason is forced to face the shocking truth. Magic is real. And Reason is magic.
