Diesel - The Mavericks, #13

Traveling to China to retrieve a kidnapped scientist shows Diesel the depths of human depravity. Not that he needs more proof. He's been doing this type of work for a decade. This is the first time though the person he was rescuing was this interesting. Eva Langston had been kidnapped while walking across the street and then locked up in a lab half a world away. Joining two other scientists, both letting her know there was no escape, she refuses to give up hope.
When the rescue does come, it wasn't smooth or easy. Still she was damn glad to be free. Until she realizes that freedom is a long way off, as, one by one, her science team is picked off, leaving her the last one to be dealt with.
