Rainy March is a proud, third-generation Book Witch. 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. 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 her magical gifts. But when her beloved grandfather disappears, there’s only one person she trusts to help her solve the case: the Duke.

As boys, Jeremy Cox and Rafe Howell went missing in a vast West Virginia state forest, only to mysteriously reappear six months later with no explanation for where they’d gone or how they’d survived. Fifteen years later, Rafe is a reclusive artist who has no memory of what happened during those months. Jeremy has become a famed missing persons’ investigator and is the one person who can help vet tech Emilie Wendell find her sister, who vanished in the very same forest as him and Rafe. The two missing boys were in a magical realm filled with impossible beauty and terrible danger. He believes that they will find Emilie’s sister there. However, Jeremy has kept Rafe in the dark since their return for his own inscrutable reasons. But the time for burying secrets comes to an end as the quest for Emilie’s sister begins.
