Evan Tanner can't sleep. Ever. Which gives him plenty of free time to get involved in lots of interesting endeavors in all sorts of exotic locales. Now Tanner's in Thailand with a partially baked plan and a butterfly net, hoping to snare a beautiful missing chanteuse who's metamorphosed into an international jewel thief. Tanner hopes everyone will buy his disguise as a rare butterfly researcher. And everyone does . . . Except the guerilla band holding him captive. They intend to remove his head when the sun rises, so Tanner must put his fate in the hands of a randy Thai youth who will do anything for a woman, even set a suspected spy free. Soon they're running through the jungle together, chased by bandits, soldiers, and yellow fever, and racing headlong into the heart of darkness--and into the flames of war.
