This is book number 2 in the Dark Elements series.
ONE TOUCH CAN HEAL Layla Shaw is trying to pick up the pieces of her shattered life. Her best friend, Zayne, is forever off-limits thanks to her mysterious power of a soul-stealing kiss. Suddenly, the Warden clan that has always protected her is keeping dangerous secrets. And she can barely think about Roth, the forbidden demon prince who understood her in ways no one else ever could. Rock bottom is only the beginning once Layla's powers finally start to evolve. She's offered a tantalizing taste of what has always been forbidden, finally getting what she has always wanted, but with hell literally breaking loose and the body count piling up, the price may be higher than Layla is willing or able to pay.
