Loved Sunstroke by David Kagan and found it to be the finest SF thriller I've ever read, more terrifying and educational than anything by Michael Crichton or Clancy. Sunstroke's subject matter is about the world we live in, right now, 2009. It just has to be made into a big blockbuster motion picture. 5 stars for Sunstroke by David Kagan. Bought the book a couple weeks ago after hearing Sunstroke's author, David Kagan being interviewed by Art Bell on the worldwide "Coast-to-Coast AM" radio program . This is the show that interviewed Dean Koontz and Star Trek's William Shatner. Kagan was really great when he explained how these space solar power satellites that fire off microwave beams at earth actually work, and what could happen if they malfunction. The U.S. Pentagon and private sector companies are developing this type of satellite for deployment in orbit. Not exactly a very comforting thought. 5 stars for Sunstroke by David Kagan.
