About the book: 2024 / Near future. Controlled thermonuclear fusion gave humanity cheap energy, a breakthrough in genetics made it possible to create new, improved people. In this serene world, something monstrous is happening: two scientific centers in China and Europe disappear without a trace, as if they are being wiped off the face of the earth. During the investigation, government agents realize that they have never encountered anything like this in their lives, and the enemy is superior to them both intellectually and technically. And then they find out that an incredible discovery somehow relates to the matter: the speed of light is no longer constant, it has begun to increase. A few years earlier, astronomer Wang Haicheng, during routine work on the FAST telescope, catches several unusual signals. Two of them indicate the existence of two Dyson clouds in the Universe, artificial spheres that envelop entire star systems. And the third carries encoded information. And it will irreversibly change the fate of not only Wang Haicheng, but of all humanity.
