Mattie Sharpe—seventeen and bored in L.A. —is getting into trouble. She gets into even more when she's whisked to Cavernis, a world teeming with dragons. But these are dragons as you've never seen them: they are fussy gourmets; work as lawyers & CPA's; and attend their school ASH, where they take classes like TNS ("Tails, Nails & Scales"). Reuniting with her childhood friend, Mattie learns why she’s been brought there, and even heads ASH’s rowing team, Skull & Bones. She learns how to be a knight from the mysterious Eli, a small mute dragon…or is he?
