Her hands clenched. She really wasn’t this much of a bitch. But goddamn Riley had a way of lighting her fuse. “Sorry, I don’t beat defenseless puppies.”

He laughed. He actually laughed. She hissed at him. “What’s so funny?”

“We both know who’s the dominant here . . . and you’re not it.”

That did it. She was a sentinel. So what if he’d been a lieutenant longer? That didn’t change the fact that she occupied the same place in DarkRiver that he did in SnowDancer. The wolf had crossed a very defined line—and since she couldn’t have sex, she’d settle for violence.

Feeling more than a little feral, she pounced.

Riley was ready for her. He took the kick on the thigh without flinching, but stopped her punch with a single hand. She was already shifting, sliding into the next position, ready to take advantage of any vulnerability. He blocked every one of her moves, but made none of his own. “Fight!” she yelled. She needed a good, sweaty workout—it would take some of the edge off the gut-wrenching fury of her need. Her booted foot connected with his ribs.

She heard a grunt and grinned. “Not so fast are we, wolfie?”

“I was trying,” he said, blocking her next set of blows with his arms, “not to hurt you.”

“I’m not a frickin’ princess,” she muttered, aiming for the most vulnerable part of a man’s body—yeah, yeah, it wasn’t fair. But Riley had asked for it. Oh, man, had he asked for it. “ ‘Kitty’ this, Kincaid.”

“Damn it, Mercy!” He grabbed the foot that had been about to connect with his crotch and flipped her. Effortlessly. Gasping as she realized exactly how much he’d been holding back, she twisted in midair and came to an easy landing on her feet.

“I’ll give you one thing,” he said, crouching opposite her as they circled each other. “You know how to move . . . kitty.”

Adrenaline shot through her, a hot, liquid fire. “Better than a jumped-up sheepdog anyway.” She kept her tone even, but she was sweating under the slinky black tee she’d changed into for the dancing, her heart beating at a rapid pace. “Claws out,” she said and that was the only warning she gave as she went for him.
