Adelle and Connie have been best friends for years, united by their love of a little-known novel called Moira. Unable to reach Moira's reclusive author, Robin Amery, the girls have to settle for reading the book over and over again, dreaming about how much better their lives would be in the world of this romantic fantasy. When the girls are tempted by a mysterious purveyor to enter the world of the book, the hardly suspect that it will actually work. And when they find the world of the novel turned upside down, the lavish balls and star-crossed love affairs now interlaced with unspeakable horrors, the girls realize that something sinister is behind their foray into fiction--and they will have to rewrite their own arcs if they hope to escape this nightmare with their lives.
