Some loves will last ’til your dying breath
Every choice has consequences—but seventeen-year-old Layla faces tougher choices than most. Light or darkness. Wickedly sexy demon prince Roth, or Zayne, the gorgeous, protective Warden she never thought could be hers. Hardest of all, Layla has to decide which side of herself to trust.
Layla has a new problem, too. A Lilin—the deadliest of demons—has been unleashed, wreaking havoc on those around her…including her best friend. To keep Sam from a fate much, much worse than death, Layla must strike a deal with the enemy while saving her city—and her race—from destruction.
Torn between two worlds and two different boys, Layla has no certainties, least of all survival, especially when an old bargain comes back to haunt them all. But sometimes, when secrets are everywhere and the truth seems unknowable, you have to listen to your heart, pick a side—and then fight like hell…

Every touch has its price
Layla Shaw is trying to pick up the pieces of her shattered life—no easy task for a seventeen-year-old who’s pretty sure things can’t get worse. Her impossibly gorgeous best friend, Zayne, is forever off-limits thanks to the mysterious powers of her soul-stealing kiss. The Warden clan that has always protected her is suddenly keeping dangerous secrets. And she can barely think about Roth, the wickedly hot demon prince who understood her in ways no one else could.
But sometimes rock bottom is only the beginning. Because suddenly Layla’s powers begin to evolve, and she’s offered a tantalizing taste of what has always been forbidden. Then, when she least expects it, Roth returns, bringing news that could change her world forever. She’s finally getting what she always wanted, but with hell literally breaking loose and the body count adding up, the price may be higher than Layla is willing to pay…

Layla just wants to fit in at school and go on a date with Zayne, whom she's crushed on since forever. Trouble is, Zayne treats Layla like a sister--and Layla is a half demon, half gargoyle with abilities no one else possesses. And even though Zayne is a Warden, part of the race of gargoyles tasked with keeping humanity safe, Layla's kiss will kill anything with a soul--including him.
Then she meets Roth--a demon who claims to know her secrets. Though Layla knows she should stay away, it's tough when that whole no-kissing thing isn't an issue. Trusting Roth could ruin her chances with Zayne, but as Layla discovers she's the reason for a violent demon uprising, kissing the enemy suddenly pales in comparison to the looming end of the world.

Dez wasn't just Jasmine's crush. A gargoyle Warden like Jas, he helped her come to terms with her destiny—fending off demons and maintaining the balance between good and evil. He was her everything…right until the moment he disappeared without a trace. It didn't help that Jas's father had just announced that she and Dez would one day be mated. Hard not to take that personally.
And now he's back, three years older, ten times hotter, ready to pick up exactly where they left off. But Jas isn't taking that risk again. Dez has seven days to meet all her conditions and earn back her trust. Seven days filled with terrifying danger and sweet temptation. Seven days to win her heart—or shatter it all over again...
