Obsidian. Alien Daemon is obnoxious for a reason, he is protecting his family and his species, by not getting to know the cute next door neighbor, Katy. Katy of course just thinks he's obnoxious. Then he saves her life. Unfortunately that puts an alien mark on her. Now he feels obligated to protect her until the mark wears off. This gives them plenty of time to trade barbs and get to know each other. But this is not just a romance. There is plenty of action too. There is a second alien species, who would like nothing more than to kill all of Daemon's kind and steal their powers. Now Katy is in the middle and learns up close and personal just how deadly this undercover war is.
