Hana wants to know everything about the world around her. When she starts asking questions, her mother gives her a book. She learns so much, but now she has even more questions! She also has a big mission: she will read all the books—every single one! She reads every book in her house…and then her friends' houses…and then the whole block. Nonfiction, fiction, romance, mysteries, and science fiction. But when her mother takes her to the downtown library, she realizes there are a lot more books than she thought…way more. Maybe she can't really read all the books—now what?
