Professor Charlotte "Charlie" Reynolds assumes that the weather is the only thing she has to worry about when she prepares to lead the last backpacking group of the season up Tempest Mountain. Joined at the last minute by sinfully sexy Jake Nelson and his beautiful young companion, Charlie is caught up in a dangerous whirlwind of nature, illicit activities and a man she can't seem to resist. Agent Jake Nelson knows his latest mission to secure evidence will be dangerous and potentially put the entire group of hikers at risk. But when the feisty Dr. Reynolds catches his eye, he's torn between the need to protect, and the desire to possess.
