Kenna Mathews is an ordinary girl-or so she thought. On her sixteenth birthday, she discovered that she was part of a group of elemental warriors that were destined to save the world, and that she was the elemental of water. There is one more girl and two boys. The girls name is Olivia, she is the elemental of earth. Jack is the elemental of wind. Then there's Cole, the elemental of fire. Together they are meant to save the world from shadows, warriors driven by pure hatred and darkness, but can they do it? Or will they destroy each other first?
