The enemy of my enemy. Shalygin V.

Many thousands of years ago, a technologically developed earthly empire created a portal that opened the way to distant space. A side effect was the distortion of time and space, connecting several parallel realities. Nowadays, imperial space wanderers decided to return to Earth, but found themselves not in the world from which they flew away. Local residents are ready to repulse the Armada of the Cosmic Empire, and they are on their side water - strange creatures from another neighboring world. Major of state security Sergey Danilov, a man with non -standard skills and white spots in biography, does not believe in the disinterestedness of water, so he helps the imperial intelligence officers find out who lured their fleet and why. The case is so serious that even the spies of the cosmic community of Harmore, the eternal enemy of the empire, perform on the side of Danilov and the scouts. The team of the former enemies will have to thoroughly work to reveal the plans of the water. After all, otherwise the matter can end in the war in all related realities, including the one in which they know the real biography of Danilov.
