Surface [EPUB ebook] 

The New Power speaks. And Sam answers. Just months after the pivotal Battle of the Water Tower, sixteen-year-old Sam Cutter remains at the center of an escalating global power struggle. What seems like a reckless move may save the world or it may tear it apart. The Master is acting. War has officially been declared. The time of shadows has past. With little time left, Sam and his friends, including the world’s immortal Royals, must gather an army to rival the New Power. The Sky Nation and the Water Nation have long resisted the corruption of the New Power. The Surface cannot afford to ignore it any longer. They must rise up and fight. Hope must return. One Surface runaway may be the light in the dark that revives a nation in dire need. The Three Kingdoms must unite or they will fall.
