Twelve-year-old Ava finds an old pencil in her family's junk drawer and discovers, during a math test, that it will answer factual questions, so she and her best friend Sophie have a great time--and Ava grows in self-confidence--until the pencil reveals a truth about her family that Ava would rather not know.
