The Cowboy and the Demon by Julia Talbot

Demon businessman Phillip Darque and his mate, vampire cowboy Cody Knight, have been estranged for decades. Phillip stayed at the corporate offices, while Cody ran the day to day business of the Midnight Rodeo. But when Cody is kidnapped as part of a family coup in the Darque demon clan, Phillip decides he’s had enough of them being apart. No one is allowed to hurt his mate, especially not his worthless, politically motivated uncle.
When Cody is kidnapped, he knows he’s going to die, and he regrets the stubborness that has kept him apart from Phillip all these years. Phillip has something his uncle wants, and Cody knows he’s just means to an end. But then Phillip comes to his rescue, saving him from final death.
Can Darque and Knight become a team once more and conquer not only their enemies but their personal demons as well?
