We have a brand-new entrant to the oil-eating-bug-runs-amok tradition: the self-published novel Petroplague. It’s a Crichton-esque thriller written by microbiology professor-turned author Amy Rogers, who says she aims to “blur the line between fact and fiction so well that you need a Ph.D. to figure out where one ends and the other begins.” The plot involves a batch of experimental, oil-hungry bacteria inadvertently loosed upon Los Angeles, which proceed to wreak a near biblical swath of destruction. Part ecology lesson and part cautionary tale, Petroplague is an entertaining entrée into the subject of oil depletion and its implications for society, human health and the environment.
