The Name of the Star by Maureen Johnson
I don’t usually read YA (mainly because I’m an OA), but my daughter ordered this for a presentation she’s doing in library school (well, technically, it’s called “information studies”, and she’s getting a master’s this weekend under the If You Can’t Get a Job, Get Another Degree plan). She knows about things. Book things. So I fully intend to casually walk into her room and distract her (Look! Halley’s Comet!) and subtly lift it.
