Katharine Geryon is living the life her family name has dictated, and why not? After all, it has given her a good job in the family company and a fine life with all the things she should want. But all that changes as increasingly disturbing events begin to occur: soot stains on the carpet, glimpses of strange black animals, and cryptic messages written on her bathroom mirror. Baffled and afraid, Katharine begins to doubt her own sanity.
At the same time, two charismatic men enter her life: Allistair, her new assistant at work, and Zachary, a well-heeled neighbor who just moved into her building. Katharine soon finds each of them inextricably entangled in her affairs. As her life becomes stranger and her dreams more terrifying, she realizes neither man is what he seems and that she's caught in something far beyond her own comprehension. For the first time, she must reach beyond her own boundaries.
