The Throne of Fire by Rick Riordan

It seems silly at this point to have to say that Rick Riordan has written another rip-roarin' young-adult adventure. What else is he going to do?

Following the near-cataclysmic events of 'The Red Pyramid', Sadie and Carter Kane have been training a young batch of magicians to help them in their struggles against forces of chaos. While these trainees play an important role, with really only one exception, most of their action is off-screen. -Hobart  N.
