(Black Knights Inc. #6) Hell for Leather by Julie Ann Walker (epub,mobi,pdf) - {@rv!nd}

Only the most urgent crisis could force Delilah Fairchild to abandon her beloved biker bar and ask the surly Bryan "Mac" McMillan for help. Her uncle—the man who raised her—has vanished into thin air, and Mac is the only person with the right connections to help her find him. What the ex-FBI agent has against her is a mystery...but when the bullets start to fly, Mac is her only chance of finding her uncle alive.

Mac knows that beautiful women can't be trusted, but he has to put his natural wariness of Delilah aside in order to help her. With the clock ticking, Mac and Delilah find themselves holding on to each other in the wildest adventure of their lives.
