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. If she’s ever caught with him again, she’ll 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. But when her beloved grandfather disappears and a priceless book is stolen, there’s only one person she trusts to help her solve the case: the Duke. Their quest takes them through the worlds of Alice in Wonderland, King Arthur, and other classics that will reveal hidden enemies and long-buried family secrets.
