Aliens have arrived with capabilities we can hardly imagine. But they refuse to communicate with us Why do they ignore us, and what do they want? Tom Kingsley is an astronomer at the right place and the right time to get the first photographs of the alien spacecraft. As a result, he becomes the leading scientific expert on the aliens and their technology. (When you are the only one in a field, you are the expert.) Tom and his team work to understand the science behind the aliens' remarkable and overwhelming technologies and the powerful and bright "stars" that they begin to place in orbit about the earth. As governments, the scientific community, and ordinary people try to understand and deal with the situation, the number of these "stars" slowly increases. Soon the Earth will grow warmer. And neither Tom, nor anyone else, can imagine a peaceful purpose for these "stars." This is a hard science fiction novel situated in the very near future. It is written by a former "rocket scientist" and part-time engineering professor. It contains a brief appendix for those who desire a more detailed explanation of the science that is the basis of this novel.
