Rainy March is a proud third-generation book witch, sworn to defend works of fiction from all foes real and imaginary. With her magical umbrella and feline familiar, she jumps into and out of novels to fix malicious alterations and wrangle characters that go off-script.Book witches live by a strict code: Real people belong in the real word; fictional characters belong in works of fiction.... Do not eat, drink, or sleep inside a fictional world, lest you become part of the story. Falling in love with a fictional character? Don't even think about it.Except Rainy has fallen hard for the Duke of Chicago, the dashing British detective who stars in her favorite noir series. After their illicit romance is exposed, Rainy is forbidden from ever seeing her fictional lover again, lest she be expelled from her book coven-and forced to give up the magical gifts that are as much a part of her as her own name.When a priceless book is stolen from her home, there's only one person she trusts to help her get it back: the Duke. Thus their shared quest begins through the worlds of Alice in Wonderland, The Great Gatsby, and other classics that will reveal hidden enemies and long-buried family secrets.
