The Grimm Legacy by Polly Shulman
Elizabeth just got a job as a Page at the New York Circulating Material Respiratory, a library that lets patrons borrow historical objects (both normal and magical). She is most intrigued by the Grimm Collection, a high security section filled with magical objects from the famous fairy tales. When the objects start to disappear and Elizabeth becomes the number one suspect, she takes matters into her own hands to find the real thief.
This magical mystery is great for all fairy tale lovers and will you have wishing that the New York Circulating Material Respiratory was a real place!
