The Storm Lords

The heat took everything from his parents, his voice when the local cure for heatstroke poisoned him, and the trust of his fellow villagers, who branded him a water thief. It would have claimed his life when he was deemed unworthy of precious resources and left in the sun to die, had not a strange man named Kristoff ridden in on the wind and told Rowen he had power.
Rowen works hard to become a Storm Lord, one of a secret magical group that brings storms to break the heat waves overtaking their world. But Rowen is starting his training at a disadvantage since he cannot speak and is much older than the other novices. The desire to please Kristoff inspires him to persevere even more than the threat of being sent back to his village to die should he fail. Still, he cannot gather rain, and when his abilities manifest, they are unlike anything known to the Storm Lords. Unless Kristoff can help him control his deadly powers, the entire world will be in danger.
Kristoff might be among the mightiest of the Storm Lords, but he’s never been a mentor before. For a chance to be with Rowen, he’s willing to risk everything.
