Colin. Council Enforcers, #16

Colin has been living half a life for the past twenty years, ever since his father caught him kissing William. Instead of standing up for their relationship, Colin allowed William to be thrown in jail and married the woman his father chose for him. He loves his two sons and even Justine, but they were never meant to be together, and they'll never be truly happy as a couple. That suits Colin just fine because he doesn't deserve to be happy.
His son Brandon does, though, and when Colin's father decides to arrange a marriage for him, Colin finds the courage he never thought he had and finally stands up to him. A half-shifter created in a lab, Matt has been working undercover for the past fifteen years with very little time as his real self in between cases. When he gets shot and realizes he won't be able to go back to his job, he's surprisingly relieved.
He'll finally have time to be himself and to cultivate his relationship with the few friends he managed to make in between jobs. And best of all, he's met his mate. Maybe now they can get to know each other and see what's possible. Things aren't that easy, though. Even after Matt and Colin talk, Colin is still married, still guilt-ridden over the pain he caused William, and still terrified of his father.
Justine finds her courage first and tells Colin it's time for them to get divorced. He agrees-but can he overcome his terror and stand up for himself and his mate?
