Shane. The Mavericks, #12

Her kidnappers demanded Shane arrive. Finding out his best friend was held as a pawn just pissed him off. Finding out rescuing her was a test made him seriously angry. He hates being used. These men mean business though, as Shane finds a body count too high for comfort. Shelly knew Shane would come for her. No way he wouldn't. She was lucky to have Shane there for her, especially when learning a second woman had been kidnapped and held for over six months.
The simple rescue of Shelly turns into something more to find this second woman. But is there one killer boss out there or two? As the pair try to secure their own freedom, it gets even murkier, until finding a way through is paramount. Otherwise no one gets a happy ending.
