Playing With Fire by Godiva Glenn

Chell of the Blue Mountain clan isn’t a woman that backs down, even after she’s been kidnapped, and her leadership temporarily stolen in an underhanded coup. It’s taken time, but now she’s on top and in charge where she belongs. Her next step is to secure her bloodline, which means she needs a mate.
Her soul mate is part of a package deal, though, and two scorching hot human firefighters wind up capturing her attention.
But Chell wasn’t looking for a human, much less two. Her world is dangerous, and her clan could benefit from the power of a shifter.
While emotions and chemistry are getting too hot to handle, a love from her past emerges and threatens the balance of their romantic trio. And to top things off, she discovers that more treachery is afoot.
It looks like this bear’s going to need to put out some fires and kick some ass.
