Kiss of the Betrayer (A Bringer and the Bane Novel)

For fifteen years Luc Le Daun has blamed himself for the death of the woman he loved. His secret guilt has led him into a life of danger, risking all and committing to none.
Killing Luc Le Daun has been all Jade Kendell has thought about for years. But when her plan goes awry and she's brought into the Bringers' fold, her own dark secret threatens to be revealed. Desire for a better life wars with a promise made long before she understood the ramifications.
In a deadly mission, Jade and Luc embark on a journey into the Shadow World. As they attempt the impossible, ignoring the attraction growing between them becomes harder to deny. The slightest misstep could mean the loss of their souls and give the Demon King exactly what he needs to open the Abyss of Souls and annihilate the Bringers.
