Predatory Nature

33-year-old Ryker Adams is the Alpha of one of America's strongest wolf packs, the 'Adam's Creek Pack'. Right after he turned eighteen, he found his mate, Tessa, and they fell instantly for one another. Even though she was human, she came from a family of shifters and things couldn't have been more perfect. But a month before the mating ritual was to take place, and the alpha title was passed down to him, Tessa passes away suddenly. The devastation nearly killed Ryker, and if he survived through it, he swore to never replace her with a chosen mate.
He eventually recovered from her loss and became alpha, but he was never the same again, becoming cold and ruthless. Now for the last fifteen years, he has ruled his pack with an iron fist, and as he swore, he never took a chosen mate. His life was just as he wanted it, but little did he know, the powers that be were about to change all that.
Casey Stevens is a beautiful 24-year-old shifter, the childhood best friend of Ryker's younger brother and beta, Alex. Both their families had been the closest of friends for many years, and allies to one another. Casey is well known throughout Ryker's pack and loved by all, coined the packs 'Angel of Light". But what most didn't know, is that Casey hides a dark secret. A secret that could put herself, and the lives of everyone She knows and loves in danger. Casey is a hybrid shifter, half werewolf, half vampire.
Her father, the alpha of her pack, 'The Shadow Creek Pack' and her mother, who was a hybrid herself were true mate's. Though her pack was perfectly fine with the fact that their Luna was a hybrid. Most other packs, and supernatural species were against mixed breeding. And it was a year ago, that one of those packs, a rival pack, launched a surprise attack on her pack that got her mother killed because of what she was. The loss of her mother, and the packs Luna was only the start of a war that would bring both Casey and Ryker together...
