In the sequel to the critically acclaimed The League and the Lantern, Jake Herndon must once again fight off dangerous intruders. This time the mystery is taken to a whole new level. After their back-to-school night became a frenzied fight for survival in Book 1, seventh grade has finally settled down for Jake, Lucy, and TJ. Of course, they still have your basic Level-Three humiliations: awkward hygiene challenges, toxic nicknames, and science fair debacles. But at least nobody is running for their life. That all changes when dangerous intruders descend on the historic Chicago hotel Jake calls home. After a daring escape, the three friends find themselves fugitives on the run, chasing a series of cryptic messages that lead to a mysterious plot to steal Civil War codes that hold importance today, a shocking betrayal, and more stunning family secrets.
