Alpha Power by T J Maguire

The Supernatural live in secret among us
Vampires
Shifters
Demons
Mages
Governed by their own societies and laws, one in which Shifters and Vampires have been enemies for millennia
When a rogue Werewolf Shifter stumbles into Vampire territory she meets an ancient, powerful and mysterious Vampire King
Their attraction to one another is swift and undeniable, despite thousands of years of war and bloodshed between their people
When dark, malevolent forces threaten the fabric of what they could build together, they’ll have to fight and fight hard for what it is they want
It will be dark
It will be violent
It will be bloody
But if they can stick together, they just might make it out alive
