"A charming, moving, funny, and ultimately very surprising story." --Wendy Mass, New York Times bestselling author of 11 Birthdays

What if your pencil were MAGICAL?

When Ava Anderson finds an old blue pencil in her family's junk drawer, it doesn't seem like anything special. But then she writes a question in the margin of her math quiz, and she hears a voice loud and clear--one that nobody else can hear--and it tells her the answer!

With the help of her best friend, Sophie, Ava sees that having a magical, all-knowing pencil can be very handy in middle school. But as Ava's reliance on the pencil grows, the truths it reveals about herself and her family lead Ava on an adventure she never expected.
