Wizards and the First Two Whole Numbers (Points of Expansion)

After a year apprenticed to a bookkeeper, Ellie has given up her dreams of learning magic and having adventures. She knows her father is right–that she should be grateful to work for the old mathematician. No, she doesn’t want to be a farmer, but Ellie can hardly see the difference between growing onions and counting them. But when her father is taken captive by a powerful and dangerous wizard, she takes an unexpected journey with a new teacher and the frustratingly positive son of a fisherman to learn more about her talents and confront the man with the ability to manipulate math’s fundamental building blocks and her perception of reality.
