"A British astronomer, Thayer, high on Darwin and other progressive scientists of [his] age, has come to believe that beings more highly evolved than us are alive on Mars (he has evidence) and that there will be a perfect moment in which we can signal to them that we are here, too. He gets the support and funding for a massive project to build the Equilateral, a triangle with sides hundreds of miles long, in the desert of Egypt in time for that perfect window. But as work progresses, the Egyptian workers, less evolved than the British, are also less than cooperative, and a bout of malaria that seems to activate at the worst moments makes it all much more confusing and complex than Thayer ever imagined"--Amazon.com.
