Werewolf in Rusted Armor (Werewolf Knights #3)

Youngest werewolf shifter brother Quin is... if not happy, content with his life. He runs a bar, and he rescues folks who are abused or downtrodden, and if he feels like a fifth wheel around his brothers and their mates, well, that's on him. He just needs to remember that he's not like his brothers Symon and Rian, and let it go at that.
When jaguar shifter Thiago follows a lost soul to Denver as part of his work as a PI, what he finds is the hottest werewolf he's ever seen, Quin. And since Quin is also working to rescue the same person he is, he has an excuse to hang around and make nice with Quin.
The two of them have to navigate a new relationship and a ring of human traffickers who threaten to tear them apart as well as taking people right off the streets. Can these two secure their mate bond while solving the mystery for good.
