Vile Magic — Holly Hook

Alyssa has just done what Thoreau wanted by waking up the Death Magic inside of her -- and Xavier's not happy about it. But that's the least of their problems. Now that Thoreau shares a body with the former leader of the Underground, he now knows where she and her friends are hiding and the days of the Underground are numbered. As he closes in, Alyssa and Xavier now have no choice but to find a way into the Infernal Dimension to rescue their comrades, but the price might be too high. By saving her father, Alyssa may be forced to awaken yet another terrifying piece of herself, one that will bring Thoreau that much closer to ending the world.
