In a slightly fantastical New York City, one very special library branch has been designated for possible closure. Bookish, socially awkward Pearl, the daughter of the librarian, can't imagine a world without the library—its books, its community of oddballs, its hominess. 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 who might just be her first friend, an older boy she has a crush on, and a pack of raccoons who can read and write—she just might be able to.
