Emmett might not have a job. He might not be going to school. He might not have any friends. Heck, he might not even be all that happy. But he's clean; that's the important thing. And all that spare time? It means he can really focus on screwing up his friendship (and absolutely nothing more than friendship) with Jim, who just happens to be the most important person in his life.
When their friend Chloe shows up at their apartment, being chased by men with guns, Emmett and Jim find themselves dragged into a conflict they don't understand. A year ago, they saved Chloe's life from a band of supernatural killers. Now, it seems someone is after her again. It's up to Emmett and Jim to stop them, which might be easier if they could figure out why everyone wants her.
It won't be that easy, of course. When Chloe's on-and-off-again girlfriend gets taken hostage, Emmett and Jim will have to race to save her. But an invisible war is raging all around them, and they've just stepped into the crossfire.
