Robert Bingham's Lightning on the Sun is a third rate thriller, a failed homage to Robert Stone's Dog Soldiers, which is a vastly superior book. Bingham did take Stone one step further, though, by OD'ing before he could see this one published, but that's his only "victory." Let's see, we have our seedy East Asian (Cambodia) location, our drug and alcholic-addicted protagonist, our brainy, hot Stateside drug accomplice, our amoral drug trafficking thugs, and our plot that has it all go wrong. You don't need this one, but check out Dog Soldiers, or even the movie version of it, Who'll Stop the Rain, with a young Nick Nolte and a ravishing Tuesday Weld. Ooh, Tuesday Weld.
