White Sand. Book 1. Time of Change

On the planet Taldain, one side of which is bathed in the rays of a relentless sun, while the other is forever plunged into darkness, live the masters of sand. By controlling sand, they create incredible things: they erect huge... buildings, fight, and even fly.
Kenton is a headstrong and bold young man who does not believe in talent, only in perseverance. Deprived of outstanding abilities, he has strived since birth to prove to everyone around him that even he can achieve the highest rank among the masters of sand and become a mastrell. But one day, people from a hostile clan kill his father and nearly all of his comrades. Miraculously surviving the bloody massacre, Kenton intends to uncover the truth about what happened. He does not doubt: someone weakened the masters of sand and convinced the enemies to attack at the most unexpected moment.
Could there be a traitor among his own?..
