Kristen Matthews has worked for months to ensure that the Nature Station's first Eco tour goes off without a hitch. But hauling a busload of nature lovers around the Door County Peninsula in Wisconsin has its stressful, and oftentimes, freakish, moments. Expecting breathtaking views of fall foliage and striking Lake Michigan waters, it's a shock when one of the passengers ends up having her breath taken away--literally Longing for placid waters, Kristen and her team spend what should be a relaxing getaway working to uncover which one of the travelers is the killer, before the trip--or another life--comes to an unfortunate end. Travel along with the Nature Station crew, as they explore beautiful, but possibly dangerous, waters.
