In their second trip through the enchanted library, the new key lands Cleo and Evan in the middle of a spy story, where their impossible mission is to stop a traitor who calls himself Viper--and they find themselves working with the replacement librarian, Ms. Crowley, whose exact role in their adventures is becoming increasingly mysterious.
