No Mercy by Sherrilyn Kenyon

sun didn't shine--she had to force herself to ignore that obvious pun. It was like the sun didn't exist in that realm...and it had to be an alternate realm. There was nothing about it to say it was the human world and it looked completely different. An odd combination of an ancient civilization and a modern one.
                Suddenly the demon was in a hall where Daimons gathered in a number she would have never thought possible for them. There had to be well over a thousand Daimons and they spoke in a language she couldn't identify.
                Crud. She spread her palm deeper into the ick on the floor to get a better immersion into the demon's last memories.
                The room around her spun until she was in the body of the demon. She could hear what he heard, feel what he felt, and see everything through his bloodred eyes. The roar of the Daimons made her ears hurt as she tried to wade through them.
                Her master was summoning her and she was desperate to reach him. He was in pain. She could feel it and it made her own body ache. It was her duty to release him. To fight and protect him...
                A male Daimon grabbed her brutally by the scruff of the neck and pulled her forward to a dais where two black thrones were set. Each one was heavily carved to resemble human bones--something no doubt meant to intimidate all who saw it and boy did it ever work on the demon as he faced the throne's occupants. A gorgeous man with short black hair sat in one and in the other was a beautiful blond woman whose eyes were so cold they seemed brittle.
                "Can we eat this one, my lord?" the Daimon holding him asked.
                The man on the throne shook his head. "Slugs are soulless. Servants. They're not worth our time. Besides, he'd give you indigestion."
                The Daimon made a sound of disgust before he flung the slug demon away. It was then the demon saw his master....
                He was on the floor a few feet from him, being drained by two Daimons.
                "Help me!" his master called as he reached out toward him, but he knew it was useless. There was nothing he could do against so many. The Daimons were killing his master....
                He would be next.
                The woman on the throne laughed. "Look at the poor creature, Stryker. I think you've scared him to death."
                He had, but it was more than that. His master no longer wore a human skin. He was in true winged demon form and still he couldn't fight the Daimons....
                The Daimons were far more powerful than all of the demon's kind.
                Terrified, he teleported away from the Daimons, back to the human world and to some semblance of safety.
                No sooner had he arrived than he felt the unleashing--the sensation of his master's death.
                I'm free. After all the centuries of serving under his master's cruel fist, he was now his own demon. Forever free. Joy filled him.
                Until a Daimon appeared to his right. "What do you think you're doing?"
                "I--"
                The Daimon lunged at him, cutting off his words.
                The slug demon ran.
                "Come back here, you worm! Die like your master."
                Terrified, the slug teleported again, but just as he flashed out, he felt something hit his chest like a vicious battering ram. Unable to breathe for the pain of it, he'd headed to the only place he could think of where the Daimons couldn't kill him.
                Sanctuary. It was the one establishment that protected all preternatural classes equally. The bears would make sure no one hurt him.
                He flashed into the third story of the building where humans were forbidden
