As Tortall's spymaster, George Cooper has sensitive documents from all corners of the realm. When Alanna sends him a surprising letter, he cleans out his office and discovers letters from when King Jonathan and Queen Thayet first ascended the throne, notes on creating the Shadow Service of spies, threat-level profiles on favorite characters, Daine's notes on immortals, as well as family papers, such as Aly's first report as a young spy and Neal's lessons with the Lioness. This rich guide also includes the first official timeline of Tortallan events from when it became a sovereign nation to the year Aly gives birth to triplets.
