The Darkest Torment by Gena Showalter — book slip

Driven to his death by the demon of Distrust, Baden spent centuries in purgatory. Now he’s back, bound to the king of the underworld, and unable to withstand the touch of another.

As he devolves into a heartless assassin, a mission gone awry leaves him with a bride—not his own. Famed dog trainer Katarina Joelle is forced to marry a monster to protect her loved ones.

When she’s taken hostage by the ruthless, beautiful Baden immediately after the ceremony, she’s plunged into a war between two evils—with a protector more dangerous than the monsters he hunts.

They are meant to be enemies, but neither can resist the passion burning between them. As Baden slips deeper into the abyss, Katarina must teach him to love or lose him forever.
