Representatives of an alien civilization are recruiting people on Earth with the necessary qualities into their long-range space reconnaissance fleet. One day, when sea captain Alexey Gardov was fishing, the charming Roael, an agent of the Commonwealth of Free Worlds, appeared near his tent. Sitting by the fire opposite a handsome, youthful man, Roael could not know that in front of her was the future commander of an intergalactic strike cruiser and her husband. In turn, Alexey did not suspect that under the guise of a beauty two entities were hiding - a young space scout from the capital of the Commonwealth of the planet Lega and an observer of the Forerunners. In the end, the winding cosmic roads lead the main characters to a meeting with the Creator. “Book three. The Ark" is part of the "Space Scout" trilogy.
