Fated to the Billionaire Wolf - A Fated Mates Billionaire Alpha Opposites Attract Wolf Shifter Romance #961411

 He's waited three hundred years for his mate. She's about to turn his world upside down. I've been alone for over three centuries. Watching my packmates find their true loves while I stand on the sidelines, fighting the darkness that threatens to consume me. Shadow corruption is spreading through my veins, and I'm running out of time. Then she collapses in my arms. One touch, and everything changes. The mating bond slams into me like a freight train. She's mine. After three hundred years of waiting, she's finally mine. 
But there's a problem—she's human. Or at least, she thinks she is. The omega seal blazing on her palm tells a different story. She's the last of an ancient bloodline. The rarest wolf in existence. And every monster in the supernatural world is about to come hunting for her. I break every rule to bring her into my pack. I have three days to teach her what she is, help her shift for the first time, and convince the Council she deserves to live. Three days before they exile us both. 
Three days before the most dangerous Shadow Wolf in history shows up to claim her for himself. I don't care about the odds. I don't care about the ancient prophecy that says she'll either save us all or destroy everything. I only care about one thing— She's my mate. And I'll burn the whole world down before I let anyone take her from me.
