Warper

Lox - the young assassin who can vanish in the blink of an eye - returns to battle dire threats once again.
Only months have passed since Lox and his crew did the inconceivable - killed the immortal Emperor Nal. Now with his comrade, Jolin as the new King, Lox, his Changeling girlfriend Vida, and the rest of his family are living in the very palace where they once fought for their lives. Things are great until the unimaginable happens, and mysterious orbs of energy rain down from the skies. Some are harmless, while others kill instantly.
As more people fall victim to the unknown orbs, fear grips the land. The countdown to war is given from a neighboring kingdom, and the newly-crowned Jolin finds himself being blamed for each new ill his people suffer. Soon counting himself among the fearful is Lox, whose own brother and sister have become the orbs' latest casualties. Even worse, he is starting to hear voices again, while at the same time being hunted by assassins whose powers far exceed his own.
With Vida - and help from an old enemy - Lox travels to lands few have seen. As he discovers more about an ancient power, Lox will have to defeat those who want him dead, uncover long-lost secrets, and even travel to a new world if he wants to save his siblings, and stop the war on Thera before all is lost.
