Impact
Douglas Preston

Three storylines come together in a race against the clock. A college dropout in Maine catches the path of a meteoroid streaking through the sky and sets off to find the rock and make a lot of money. Wyman Ford, a former intelligence officer (and a major character in Preston's Blasphemy), is back trying to find the source of honeys – radioactive gemstones that can cause horrific disease in their wearers as well as be used in the creation of dirty bombs. And finally, a scientist at the National Propulsion Facility is finding some strange gamma ray data coming from Mars...

Preston takes the global catastrophe by meteoroid storyline and twists it in amazingly creative ways. If you like your action mixed with science, this one is for you.
