Deadly Wolf Bite by Heather Hildenbrand

They call me a princess. An heir to a city built on the blood and bones of innocent lives.
I have no desire to rule—not if it means becoming like the family who threw me away like garbage. But there is one thing I want more than my freedom.
To save the only man in this city who thinks I’m worth keeping.
What I feel for Grey is as forbidden as it is real.
As much as I want to run away and never look back, I could never abandon him. But if I want to keep us both from being eaten alive, I’ll have to convince them all he’s nothing to me.
Worse, I’ll have to betray him to his enemies.
The only thing that can help us now is a mate bond I’m not sure exists for someone like me. There’s only one way to find out and it means risking my life in hopes of becoming the wolf I was meant to be.
This will either break the spell and make me strong enough for what’s coming—or it will be a deadly wolf bite. Either way, I can’t stand by and watch the man I love go down without a fight.
