Paula wants to win the third-grade science poster contest more than anything. There's just one problem - and her name is Cynthia Lyden.

Also known as Miss Perfect.

Cynthia, a girl with a different hair scrunchie for every outfit. Cynthia, who handwrites whole pages without a single cross-out. Cynthia, who framed her poster and brought it in a day early.

Is Paula clever enough to compete with Cynthia? And if so, will it matter? As the two girls compete, Paula makes a startling discovery that changes her desire to out-do her rival.
