AFTER OBSESSION by Carrie Jones and Steven E. Wedel.
INVITATION: When you ask him in,
INFESTATION: When he destroys your home.
OBSESSION: When he destroys your body.
POSSESSION: When there is no coming back.
This story almost stopped my heart more than once. It's riveting (and scary!) and the dual POVs are beautifully done. Congrats, Carrie and Steven--what an awesome team!!!!
From Amazon:Aimee and Alan have secrets. Both teens have unusual pasts and abilities they prefer to keep hidden. But when they meet each other, in a cold Maine town, they can't stop their secrets from spilling out. Strange things have been happening lately, and they both feel that something-or someone- is haunting them. They're wrong. Despite their unusual history and powers, it's neither Aimee nor Alan who is truly haunted. It's Alan's cousin Courtney who, in a desperate plea to find her missing father, has invited a demon into her life-and into her body. Only together can Aimee and Alan exorcise the ghost. And they have to move quickly, before it devours not just Courtney but everything around her.
Loved it, loved it! :-)
