Demon Realm by Tracy Lauren

I was on the other end of the country when the world ended, but I still felt it. It cut through my dreams, letting me know what was to come. A monster, a DEMON… and he was hunting for me. The world was crumbling and still, all I could think about was him.
The news said it was an accident, that no one ever meant for such a thing to happen. But there was no way to undo what had been done. The fabric between realities was tearing open, pulling people in. Flickers, they called them—ever expanding from the epicenter. Some people flocked towards it, but I wanted to run. They brought me closer to the demon. Every time I closed my eyes, he was there. I’d walk into an empty room and smell his scent, haunting me.
I thought perhaps I’d lost my mind, that the state of things had pushed me over the edge. My demon was becoming more real than the last bits of humanity fading around me. More and more people vanished every day, yet this demon was the only one I missed—a creature I’d never met, one that should strike fear in my heart and make my blood run cold. Instead, a part of me felt like I’d always been waiting for him. A part of me was ready… to fall into his DEMON REALM.
