Wyman Ford is tapped for a secret expedition to Cambodia... to locate the source of strangely beautiful gemstones that do not appear to be of this world. A brilliant meteor lights up the Maine coast... and two young women borrow a boat and set out for a distant island to find the impact crater. A scientist at the National Propulsion Facility discovers an inexplicable source of gamma rays in the outer Solar System.  He is found decapitated, the data missing. High resolution NASA images reveal an unnatural feature hidden in the depths of a crater on Mars... and it appears to have been activated. Douglas Preston is back with Impact, an irresistible page-turner. Join us for an evening of conversation with Douglas Preston and David Morrell, author of the riveting new novel, The Shimmer. When a high-speed chase goes terribly wrong, Santa Fe police officer Dan Page watches in horror as a car and gas tanker explode into flames. Torn with guilt that he may be responsible, Page returns home to discover that his wife, Tori, has disappeared. Frantic, Page follows her trail to Rostov, a remote town in Texas famous for a massive astronomical observatory, a long-abandoned military base, and unexplained nighttime phenomena that draw onlookers from every corner of the globe. Many of these gawkers—Tori among them—are compelled to visit this tiny community to witness the mysterious Rostov Lights. Page must solve the mystery of the Rostov Lights to save his wife. In the process, he learns that the decaying military base may not be abandoned at all, and that the government may have known about the lights for decades. Could these phenomena be more dangerous than anyone could have possibly imagined?
