Deception Lake (Harlequin Intrigue Series #1553)

"I'm not who you think I am." 

While his rodeo days have come and gone, cowboy Jack Drummond is in for the ride of a lifetime…with life itself hanging in the balance. An unexpected encounter with his old flame, Mara Jennings, triggers a series of events that Jack never could have predicted. There's just one problem: Mara isn't the same woman Jack remembers. She looks like Mara. And sounds like Mara. But reignited passions aren't enough to hide the fact that she's harboring a big secret—and hiding out from an even bigger enemy. Now, learning the truth might be the only way to stay alive. Or it could tear them apart—permanently.
