What to read after Lost Souls: Burning Sky?

In this first book in a new trilogy created by new media genius Jordan Weisman, Nathan Richards is your typical teen, one of the smartest at his school and the son of two famous archeologists, but he fails at everything because he refuses to apply himself. Never knowing his mother, who died on an archeological dig in a Mayan tomb while giving birth to him, Nathan is shocked, when on his thirteenth birthday he receives his birthright from the Mayan god Kukulkan. He is granted the ability to travel the frequencies and interact with the dead -- including his mother! Now the fate of the human race rests with Nathan, who must play a game for the world's survival -- all culminating with the end of the Mayan calendar on December 21, 2012. Now it is time for Nathan to use his newfound gifts, fulfill his potential, and save the world!
