Toby is a young tom who dreams of becoming an apprentice cat, a feline partnered with an apprentice human mage, at the King's Academy of Mages. When he is partnered with Lorn Ribaldy, the nephew of known traitor Master Hecktor Ribaldy, he learns his dreams are in jeopardy. There are those who want to keep undesirables out, and that includes Lorn and anyone associated with him. In a meeting with Head Master Cat Meredith and Head Master Mage Jalen, Toby and Lorn are offered a way to change their status from provisional to permanent: find out why Toby's father disappeared during a standard recon mission for the High Council. Now all they have to do is keep up with their homework and survive a little espionage.
