Beyond Here ...There Be Demons (The Master's Bloodline Series: Book 2‪)‬

Volunteer to become a half-human, half vampire soldier trained to kill vampires? Check. Kill a Master Vampire and then take control of his coven? Check. Get yourself arrested and sentenced to death for violating the rules of the Vampire's Governing Body--but not before escaping custody and fleeing with your family to the mountains of Tennessee? Check.
Blaine LaShomb has done it all and finally, after years of war, he’s found the one thing he’s long sought after: Family and peace. But soon, both are taken away the day several Werewolves arrive at his family's cabin--attacking him and slaughtering his mates--all before escaping with his son. Despite being blood-starved and weakened, Blaine sets out to end the threat once and for all.
…Now all he needs is to find a way to break out of prison and escape Talya, the power-hungry Alpha Wolf that’s taken him captive. And if Blaine's cup wasn't already on the verge of spilling over; there's the sudden awakening of creatures that no one has seen in over a millennia.
