Logan Wilde is accidentally drawn into the mysterious, dangerous world of the Menagerie when he discovers a griffin hiding under his bed . . . and it leads him straight to the weirdest girl in seventh grade, Zoe Kahn.

Zoe is panicking. Her family has been guarding the Menagerie for centuries. If they don't get the cubs back fast, the whole place will be shut down. To save the griffins' lives, she's willing to break all the rules, even if it means letting an outsider like Logan help. But the real mystery remains: Is someone trying to sabotage the Menagerie?

Who let the griffins out...and why?
