A warm and loving story about how a non-binary person comes to understand and accept themselves by an award-winning queer author. Every morning, when Annie's moms open up their bookshop, there's a pile of books on the counter, waiting for the right reader to come and find them. But one day, there's a book nobody comes for. Nobody ever comes, and each day the book gets lonelier, and the bookshop becomes an unhappy place. Who can the book be for, and why don't they come? Eventually, the book finds the reader who needs Annie's sister, Charlotte. Charlotte asks the family to call her Charlie now, and to use 'they them' pronouns. The bookshop cheers up. Customers start buying books again.
