Hell on Wheels

In her riveting debut, Walker delivers a mystery laced with red-hot romance. Former Marines Grigg Morgan and Nate Weller work for Black Knights Inc., a high-tech motorcycle shop that’s really a black ops group doing side jobs for Uncle Sam. After Grigg dies on a mission, his sister, Ali—Nate’s longtime crush—gets embroiled in a plot that could get her killed. Crooked Sen. Alan Aldus becomes convinced that Ali has secret files that incriminate him, and he hires Dagan Zoelner, an ex-CIA agent, to bring Ali in. Lucky for her, Dagan has a conscience, and Nate will do anything to keep her alive even as he fights his attraction to her. This first-rate thrill ride leads to a satisfying emotional payoff that neatly sets up the next book: the story of Black Knights boss Frank Knight and sassy mechanic Becky Reichert. Agent: Nicole Resciniti, the Seymour Agency. (Aug.)
