What if your pencil had all the answers? Would you ace every test? Could find out who has a crush on who? When Ava Anderson finds an old pencil, she uses it for her math quiz like any other pencil. It's when she writes a question in the margin that the magic occurs . . . as a voice that no one else seems to hear. With the help of her best friend, Sophie, Ava figures out the rules of this pencil's magic, and as they discover many uses for it, Ava's reliance on its answers grows. But when the pencil reveals a scary truth about Ava's family, she sees that the bravest people just might be those who live without all the answers.
