I can't believe I have never reviewed this book, as it is my favorite series of all time and I recommend it to people constantly. Jim Butcher is an absolute master at world building. Jim, if you are reading this, please know how many hours of enjoyment your books have brought me. You are awesome.
Furies of Calderon is set in the world of Alera, where, as people mature, develop a bond with at least one of the elemental furies of earth, air, fire, water, wood, and metal and use those talents throughout their lives. We journey with Tavi, who is fifteen and is considered a freak because he hasn't developed any furies. It's a story about how he overcomes this obstacle and learns to live on his wits without furies. But it is also a story about politics, war, and loyalties. Good vs. evil, treachery and deception, all in an epic fantasy setting.
In book 1, Tavi stumbles upon the sneak invasion of the Marat, a savage enemy whose last battles in Alera ended with the death of the Princeps. As chaos breaks out over the Calderon Valley, he has to find a way to survive on his own. Meanwhile, the First Lord is surrounded by betrayal and loyalties to the Realm are called into question, reaching from the far steadholts of Garrison to Alera Imperia.
If you love sword fighting, magical creatures, political intrigue, strong family bonds and a little bit of romance, check out the Codex Alera series. It's fantasy at its best.
