House of Ravens - The Shadow Atlas, #1

Something dark awoke inside him.Sixteen-year-old Torin will be a shadow mage; it's his destiny. But when he discovers his father's legacy is built on lies and innocent blood, Torin's eyes are opened to a dark new reality. And he wants no part of it. But, in a cruel twist of fate, Torin manifests a rare Shadow Magic power-killing with the touch of his hand-and becomes a pawn for his father's vengeance.
With blood on his hands and a future paved with death, Torin must make a choice-betray his father and do what is right, or take on his dark legacy and become the monster he's been running from.
