Twin sisters Lia and Alice Milthorpe have just become orphans. They have also become enemies. In late nineteenth-century New York state, wealthy sixteen-year-old twin sisters Lia and Alice Milthorpe find that they are on opposite sides of an ancient prophecy that has destroyed their parents and seeks to do even more harm.

With time dwindling but her will to end the Prophecy stronger than ever, Lia sets out on a journey to find the remaining keys, locate the missing pages of the Prophecy, and convince her twin sister Alice to help--or risk her life trying.
