An anonymous correspondence between two seventh graders becomes an unlikely friendship after they start leaving notes in a school library book. Bookish Jane MacDonald is seeking a new friend after her best friend Sienna moves away; reputed troublemaker Tyson Flamand stumbles upon the first note while waiting for a detention. Both end up in a race to improve Tyson's grades--and their teachers' understanding of him--so that he can help complete the school team for Jane's cherished Kid Lit Quiz competition and win a trip to the championship in Sienna's new city.
