The Last Shadow Knight by Michael Webb
The kingdom will fall. What if you were the only one able to stop it?
On the unforgiving streets of Karad, Veron grows up hungry, inexperienced, and stealing to survive. When a heist goes dreadfully wrong, he finds himself alone and desperate for a change. Opportunity arises when he discovers the last survivor of a secret organization called the Shadow Knights. Apprenticed to learn their ways, Veron develops abilities beyond anything he ever dreamed.
Meanwhile, an enemy from across the mountains comes to destroy their kingdom’s way of life, and the Shadow Knights are the only ones able to stop them. As Veron fights to survive the city, master the Knights' ways, and build a business of his own, he realizes a stark truth—fulfilling his destiny and saving the kingdom will cost him everything.
An epic fantasy for young-adult readers who love books like Mistborn, Eragon, the Name of the Wind, or the Ranger’s Apprentice.
