A New York City library branch has been designated for possible closure yet the bookish, socially awkward Pearl, the daughter of the librarian, can’t imagine a world without the library. When the head of their Edna St. Vincent Millay statue goes missing, closure is closer than ever. But Pearl is determined to save the library. And with a ragtag neighborhood library crew—including a constantly tap-dancing girl, an older boy she has a crush on, and a pack of literate raccoons—she just might be able to do it.
