Possessed

Some girls go to college after high school. Amber Pérez joined a cult. After the car crash, after she lost her brother, nothing seemed to matter anymore. So when the only friend she had left said, You wanna hang out in some parks, smoke some weed, spray-paint some anarchy signs? Amber said, Why not? None of it was, like, for real. That was before Matthias took over. Before he found The Book. All it took was one accidental step on the pentagram and, whoops, she's bonded with a demon.
Jayuul's a jerk who loves hurting people, but she can't get rid of him. Worse, Matthias will literally set her on fire if he finds out, and she can't even tell her friends, because Shannon's banging him (ugh), and Dylan's his second in command. She wants out, but how? She lives on Shannon's couch!When Amber witnesses another crash, it feels like losing her brother all over again, until she learns she can heal people just as easily as hurt them.
The demon's never had a host who wanted to do that, and. No one's more surprised than him to find out he actually likes it. Helping people not die is a serious motivator, so Amber and Jayuul hatch a plan to keep Matthias from terrorizing Miami. She just has to juggle her friends' suspicion, Matthias's growing madness, the flirtations of local celebrity and kidnapping victim "Kitty Kim" Alexander, the police, the church, and a betrayal she never would've expected.
No problem, right?
