PERSONAL DEMONS (Tor Teen, September 14, 2010)
Frannie Cavanaugh is a good Catholic girl with a bit of a wicked streak. She's spent years keeping everyone at a distance—even her closest friends—and it seems her senior year will be more of the same...until Luc Cain enrolls in her class. No one knows where he came from, but Frannie can't seem to stay away from him. What she doesn't know is that Luc works in Acquisitions—for Hell—and she possesses a unique skill set that has the king of Hell tingling with anticipation. All Luc has to do is get her to sin, and he’s as tempting as they come. Frannie doesn’t stand a chance.

Unfortunately for Luc, Heaven has other plans, and the angel, Gabe, is going to do whatever it takes to make sure that Luc doesn’t get what he came for. And it isn't long before they find themselves fighting for more than just her soul.

But if Luc fails, there will be Hell to pay…for all of them.

ORIGINAL SIN (Tor Teen, July 5, 2011)
PERSONAL DEMONS series, book 2
Luc Cain was born and raised in Hell, but he isn't feeling as demonic as usual lately--thanks to Frannie Cavanaugh and the unique power she never knew she had. But you can't desert Hell without consequences, and suddenly Franie and Luc find themselves targeted by the same demons who used to be Luc's allies.

Left with few options, Frannie and Luc accept the protection of Heaven and one of its most powerful angels, Gabe. Unfortunately, Luc isn't the only one affected by Frannie, and it isn't long before Gabe realizes that being around her is too...tempting. Rather than risk his wings, he leaves Frannie and Luc under the protection of her recently aquired guardian angel.

Which would be fine, but Gabe is barely out the door before an assortment of demons appears--and they're not leaving without dragging Luc back to Hell with them. Hell won’t give up and Heaven won’t give in. Frannie's guardian exercises all the power he has to keep them away, but the demons are willing to hurt anyone close to Frannie in order to get what they want. It will take everything she has and then some to stay out of Hell's grasp.

And not everyone will get out of it alive.
