Mackenzie McMurray must decide who is friend and who is foe in the intensifying threats on her life. At least three different suspects take her from her home on Whidbey Island, located on Puget Sound, to mainland northern Washington State, across the Cascade Mountains and as far as Coeur d' Alene, Idaho. In her search she explores hunting cabins, attorney offices, ferries, suspicious fires, and old family mansions. Oak Harbor is definitely a mystery story with just a touch of paranormal and coming of age thrown in.
