Mean Streak by Sandra Brown
Dr. Emory Charbonneau is a marathon runner and she decides to run a high altitude mountain trail in the Carolinas as part of her training. She gets off to a great start, but shortly into her run disaster strikes. Emory awakens in a strange bed looking into the eyes of a man who is not her husband. Apparently she fell while running, hit her head on a rock, and is now suffering from a very bad concussion. While she is thankful that this man rescued her and brought her in before the freezing temperatures of evening, she desperately wants to return home. But her savior does not have a phone and refuses to drive her down the fogbound mountain. As her time there goes on she begins to wonder if her rescuer actually caused her injury and is possibly keeping her captive.
I don’t think I’ll ruin anything by pointing out that Brown excels at writing gripping romantic suspense. So you know there is a love story here (and two people stuck in a cabin in the middle of nowhere kind of gives away how the romance will blossom) and that things are most likely not what they seem. There are a lot of twists and turns in the plot that will keep you guessing. A great choice on audio, the reader is really good at the different voices, especially the redneck brothers that become central to the plot.
