Magestone - David Burleyson - Bog

Once, magic was everywhere.¿Then, the magestones were all destroyed.All, except one...¿Grayson Fletcher has spent his entire life working as a blacksmith's apprentice in his family's forge. He knows his way around an anvil, but he suspects there's more to life than hot iron and sweaty aprons. So when he's given the chance to join the prestigious royal academy and train to become a fabled realm knight, he jumps at the opportunity. ¿
But between the looming threat of raiders attacking his home village and finding an ancient relic with a mind of its own, there was always something to distract him from his studies. To make matters worse, a school assignment inadvertently pits Grayson and his friends up against the evil raiders, and he'll quickly learn that no amount of training could've prepared him for what lies ahead.
