Bonded with an Alien Female

When a seventy-year-old man named Eddie visits the country of his birth, the Netherlands, nearly fifty years after he has moved to the United States, he has an odd encounter in a flea market. An elderly fellow persuades him to buy an old computer monitor, one that produces shocking images from his past. He does so-and unknowingly and drastically changes his life.
Eddie takes the old monitor home with him to America, only to be surprised when the man from the flea market arrives on his doorstep with a woman. They are from another dimension and have been observing him since birth. Now they need Eddie's help in order to prevent the destruction of the earth. The beings ask him to join their mission, and in order to make it easier for him, they clone him, giving him a younger body to house his consciousness and bonding him with the woman, whom he now knows as Jane. Their goal: to serve as the technical team that will delay and ultimately curtail global weapons development progress.
In this science fiction novel, a man works with two aliens to inhibit nuclear proliferation on earth and save humanity from itself.
