The first time Regina sets eyes on J.T. McCall's perfect posterior, she knows this sexy cowboy keister is ideal for her Way Out West Jeans commercial. J.T. rejects her offer, but Regina won't take no for an answer and follows him on his cattle drive, finagling her way into a job as camp cook. She gets more than she bargained for, however, when a vengeful killer begins picking off the cowhands one by one. Left alone, J.T. and Regina turn to one another as they race to stop a madman. Cowboy Accomplice (4), B.J. Daniels' latest in her McCalls' Montana series, is a masterful blend of humor and suspense.
