His Damaged Pack by Jena Wade

Asilo Pack lives in the shadows protecting those without a voice.
My brother warned me to run—that Highridge was no longer safe for me, but I was stubbornly refusing to leave him until it was too late, our pack Alpha leaving him for dead and keeping me prisoner, help unable to get to me.
Cooper came to the rescue, and I fell in love. My beast recognizing him as ours. The sexy old alpha kept me at arm’s length for our own safely. If Highridge knew what we were to each other, that would be the end of us.
Leaving my mate was the hardest thing I ever had to do, but I knew we’d be together again someday.
And then I got what should be the happiest news of my life: I was pregnant. I needed to find Cooper, despite the danger. Our baby deserved both his fathers and I was willing to fight to make that happen.
