Alyssa's a rare mix of supernatural according to Thoreau, the demonic mayor, and she was every reason to believe him. She's already got a rare gene that turned her into a vampire and now her enemies burn from the inside out whenever she stabs them. On top of that, biting her hot Mage battle partner, Xavier, will strengthen them both and bring her one step closer to becoming the "Dark Pentagram," who will merge Earth with the Infernal world. Therefore, it's best to stay out of Thoreau's clutches unless she wants to see Hell on Earth. But then Thoreau steals the secret to destroying the Underground, the society of supernaturals that Alyssa now calls home, she and Xavier have no choice but to go after him. Demons? No problem. Crossing the world? No sweat. Finding out whether or not Xavier likes her? That's tricky, along with learning where her strange powers came from. But none of that compares to her growing thirst for Xavier's blood, a thirst she may not be able to resist. Alyssa just might have to become the monster she's vowed never to be...
