The beginning of a fast-paced fantasy trilogy from the bestselling author of the "Dresden Files" series. Tavi is 15 years old and frustrated with his lack of furycrafting. However, a chance encounter with a runaway slave and undercover spy Amara will fling his entire world into chaos.

Jim Butcher is the author of the Dresden Files, the Codex Alera and the Cinder Spires series. His résumé includes a laundry list of skills which were useful a couple of centuries ago, and he plays guitar quite badly. An avid gamer, Jim plays tabletop games in varying systems, a variety of video games and LARPs whenever he can make time for it. He currently resides mostly inside his own head, but his head can generally be found in his home town of Independence, Missouri.
