The Shattergrave Knights

Every family has its own traditions. The Merriwether family traditions are dark magic, devil worship and insurrection. Jack and Olive Merriwether thought they were two ordinary teenagers until they learned they were descended from the murderous sorcerer Gorgyaz. Now that the truth about their ancestry is out, the government wants to take their freedom, a witchfinder wants to take their lives and the shadowy leader of the Thirteenth Division wants to take their souls. Jack and Olive never intended on following in their infamous forefather's footsteps, but they'll have to learn the family traditions to survive.
