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 in and out of novels to fix malicious alterations and rogue heroes like a modern-day magical Nancy Drew. Book Witches live by a strict code: Real people belong in the real world; 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. Which is why Rainy has been forbidden from seeing the Duke of Chicago, the dashing British detective who stars in her favorite mystery series.
