Meet Anya Winter, junior professor of magical textiles at Arcanos Hall. She spends her days designing invisibility cloaks and teaching reluctant sophomores to knit. If she can avoid her conniving ex-boyfriend and steer clear of campus politics, that's a plus. But everything changes when her secret university is unshielded by a saboteur, placing the entire magical community at risk. Joining forces with a rebellious princess and a mysterious engineer, Anya must save her school--and her reputation--before it's too late. But can she really change the world with just a ball of yarn?
