Demon Magic [Supernaturals Underground, Book 5] - Supernaturals Underground, #5

I'm now only one step from becoming the Dark Pentagram, the being the demon Cazio will use to spill hell on Earth, and I'm seriously freaking out. I've also done my fair share of bad things lately, and it really puts a damper on the fact that me and Xavier are finally free to be a real couple. But the worst is yet to come. My worst magical surprise still waits to awaken, and it's darker than anything I've faced so far. I'm avoiding that at all costs. As if. When we learn Cazio's enslaved the only beings in the world capable of killing him, there's no choice left-we get to venture into the Infernal Dimension to free them and save the world. And doing so will awaken that last scary part of me, and it just might rip us apart and take the world with us.
