Trisolarian crisis continues. Earthlings have 400 years to prevent an alien invasion. But the threat of complete destruction, contrary to expectations, does not unite humanity. Superposites defend their interests, space fleets, becoming independent political force, completely lose touch with the Earth. Total control over scientific and technical developments from someone else's civilization, many times higher in development, leaves people a chance to win. The outcome of the war will decide the projects of the "casuals" - the best thinkers of the planet.
