Emma and her friends face mysterious messages and the return of a dangerous enemy in the latest Codebreakers installment.
Emma Avery is settling into her new life at Afton Academy, even after her terrifying confrontation with the Division and Owen’s betrayal of the Codebreakers. Then secret encoded messages start appearing in Emma’s school things with ominous warnings about Leonora, the head of the Division, who seems close to finding a compass with the power to locate Sablewood’s other magical objects. Emma and Nate race to break the long-unsolved compass code, but when Nate discovers and prioritizes a different set of clues, their friendship becomes strained as they argue over what’s more important—helping the note sender or finding the compass. And when the Codebreakers land straight into a trap, Emma must confront Leonora or risk destroying the Codebreakers’ legacy forever.

Filled with mystery and adventure, The Lost Compass Clue is the propulsive and exciting story of a girl on a quest to save the world—and protect her friends along the way.
