Natalie's best friend, Zoe, is sure that the novel Natalie's written is good enough to be published. But how can a twelve-year-old girl publish a book? Natalie's mother is an editor for a big children's publisher, but Natalie doesn't want to ask for any favors. Then Zoe has a brilliant idea: Natalie can submit her manuscript under a pen name, with Zoe acting as her literary agent. But it's not easy for two sixth graders to put themselves over as grown-ups, even with some help from a couple of "real" grown-ups who are supportive but skeptical. The next best-selling school story may be in their hands -- but can Natalie and Zoe pull off their masquerade?
