THE WOLFEN STRAIN [Kindle Edition] by Chris Stevenson

Seth Anson, a ranger stationed at the Wheeler Ridge watchtower, is trying to get over a bitter divorce—working in the majestic Shoshone forest is the only way he knows how to get on with his life. Consequently, he is unprepared for the strange and mysterious woman he accidentally shoots and then must nurse back to health. As Seth and Melina form a close bond that leads to something deeper—they have no idea that the geneticist’s other creation—the result of a DNA cloning experiment gone horribly wrong—is bent on finding Melina and committing a monstrous act.
