Falcon is thirteen—too old for magic, too old for dragons and saints, too old to think about the adventures from her past. All she wants is to be an ordinary girl. But Falcon has a family legacy that cannot be denied, and, when her beloved Aunt Emily suffers a heart attack, that legacy and the magic within it may be the only way to save Emily"s life.

Falcon finds herself in New York City circa 1903, accompanied by Aunt Emily (who has managed to reoccupy
the body of her own twelve-year-old self) and Allie Cadwallader-Newton (who knows a bit about time travel, thanks to her own adventures). With the help of a few old friends, Falcon sets out to find the way home, but she soon discovers that the situation is not what it seems. And there will be impossible choices ahead.
