The Broken Empire Series by Mark Lawrence
The 3-book set of mass market paperback novels includes the below titles:
Prince of Thorns (ISBN 9781937007683): When he was nine, he watched as his mother and brother were killed before him. By the time he was thirteen, he was the leader of a band of bloodthirsty thugs. By fifteen, he intends to be king…
It’s time for Prince Honorous Jorg Ancrath to return to the castle he turned his back on, to take what’s rightfully his. Since the day he hung pinned on the thorns of a briar patch and watched Count Renar’s men slaughter his mother and young brother, Jorg has been driven to vent his rage. Life and death are no more than a game to him—and he has nothing left to lose.
But treachery awaits him in his father’s castle. Treachery and dark magic. No matter how fierce his will, can one young man conquer enemies with power beyond his imagining?
King of Thorns (ISBN 9780425256237): At age nine, Prince Honorous Jorg Ancrath vowed to avenge his slaughtered mother and brother—and to punish his father for not doing so. At fifteen, he began to fulfill that vow. Now, at eighteen, he must fight for what he has taken by torture and treachery.
Haunted by the pain of his past, and plagued by nightmares of the atrocities he has committed, King Jorg is filled with rage. And even as his need for revenge continues to consume him, an overwhelming enemy force marches on his castle.
Jorg knows that he cannot win a fair fight. But he has found a long-hidden cache of ancient artifacts. Some might call them magic. Jorg is not certain—all he knows is that their secrets can be put to terrible use in the coming battle…
Emperor of Thorns (ISBN 9780425256541): King Jorg Ancrath is twenty now—and king of seven nations. His goal—revenge against his father—has not yet been realized, and the demons that haunt him have only grown stronger. Yet no matter how tortured his path, he intends to take the next step in his upward climb.
Jorg would be emperor. It is a position not to be gained by the sword but rather by vote. And never in living memory has anyone secured a majority of the vote, leaving the Broken Empire long without a leader. Jorg plans to change that. He’s uncovered the lost technology of the land, and he won’t hesitate to use it.
But he soon finds an adversary standing in his way, a necromancer unlike any he has ever faced—a figure hated and feared even more than himself: the Dead King.
