White Hot Kiss (The Dark Elements, #1)

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.
