“If kinging were easy, everyone would do it.”

With help from his friends, Billy Smith―the unlikeliest of heroes―overthrew the corrupt General Sawtooth and claimed the Goblin Crown. But his perilous journey to save the goblin race has just begun. The powerful Hanorian Army is gathered at the gates of Kiranok, threatening to invade the goblin city and wipe out everyone within. So the inhabitants of Mother Mountain must draw on their deepest strengths for the battle to come: Billy, a burgeoning leader, crafts military strategy while fending off foes from within the goblin ranks; Lexi, her magic growing, trades firepower with the mighty wizard Mig; and steadfast Hop and stalwart Kurt set off in pursuit of a mysterious Fallen Star, perhaps their only hope for defeating the enemy―but did it awaken an even darker force in the universe? Billy, Lexi, Kurt, and the goblins soon realize the true meaning of duty, death, and destiny―and that the wages of war come at a steep price.
