Query: Awesome Desert Adventure

A good thriller and science fiction novel. Will guarantee to spoil your boredom, like mine waiting for five hours in the airport lounge.The plot mixes exciting actions along with the main protagonist's epileptic/seizure problems. Judging Greg Iles previously written and other other novels, I guess he has a medical training background, like Michael Crichton did. As most of thriller novels, eventually the doomsday has been thwarted, in the last few moments. Another predictable ending...Though a quite well-written book, it is not among the best. I give four stars for this one.
