Many millennium ago, the continents of the world were combined into one kingdom: TaLoria. The people of TaLoria were governed by the Four Guardians, sisters blessed with control of the elements. Unbeknownst to the Guardians, a secret plot to destroy the harmony in TaLoria was brewing in the heart of their adviser, Itzal. Through his cunning, Itzal caused war to erupt throughout the kingdom, leaving nothing but death and destruction in its wake. At the conclusion of the war and having failed to gain the powers he sought, Itzal took matters into his own hands and murdered the sisters. Still, one fought back, and Itzal's plans were thwarted.
Over the course of the centuries, Itzal has sought for the one who escaped his grasp, taking with her the ultimate power. Now, Cassi Greenleaf, an average girl from a small town in Oklahoma, will discover her place in this deadly game. The clock is ticking, and Cassi must find the strength within herself to face Itzal and prevent him from gaining what he most desires: her death.
