Locked in a Room with a Werewolf

Zack Bluestone thought he was being mugged when he was ambushed by several huge men. He didn't expect to wake up in chains in a creepy basement, or to be naked, or for there to be a naked man with him, who is also in chains, and looks pretty vicious. Brian Lauren is so angry with himself that it's hard to keep his inner alpha from taking over and tearing everything apart. He can't believe he was kidnapped and put in a pit, but it happened, and he has to find a way out of here before he goes wild and attacks the only other person locked up with him. The problem is that person happens to be his mate, and if Brian wants to get them out of this alive, he has to convince the man that they need to mate with each other so he can have the strength to escape before their captors return and kill Zack.
