The Codex Alera is a series by Jim Butcher. The first book is called the Furies of Calderon.
The main character is a young man named Tavi whom everyone considers a very unusual child because he has no Furies of his own. Furies are spirits of the elements; earth, fire, wind, water, wood and metal. Crafters use these elements in their everyday life, and everyone, except for Tavi, has at least one of them by the time they are teenagers.
Tavi has grown up with his aunt and uncle on their steadholt, helping to tend the sheep and other animals. One day when Tavi and his Uncle Bernard are attacked by a Marat warrior, and they get separated.
The Marat and the Alerians have been at war for several years, ever since a band of Marats had attacked and killed the First Lord's son, Septimus.
Tavi finds a young woman named Amara and get caught in a fury storm, which renders all furies unusable, and Tavi has to use all of his wits and cunning to get Amara and himself safely back to the steadholt.
Needless to say, there is a lot more going on in this book, and this is only the beginning of both the book and the series! I encourage you all to go find and read this wonderful series.
Follow Tavi as he progresses from a child to an adult that will eventually save his kingdom from an evil that causes both of the realm's largest enemy's to band together just to survive!
