Masterful thriller writer Mills returns to his series hero, former FBI agent Mark Beamon (last seen in 2002's Sphere of Influence
), with a pulse-pounding apocalyptic scenario that is terrifying in its plausibility. Maverick environmentalist Erin Neal has become a pariah after his provocative book angered both conservationists and conservatives, and a recluse after the death of his ex-lover, eco-terrorist Jenna Kalin. His solitude is interrupted when Beamon, now the head of energy security for the U.S. government, tracks him down to stop a disaster: the destruction of the world's major oilfields by bioengineered bacteria remarkably similar to ones Neal himself considered designing. The bioweapons have already infected the major Saudi sources of oil, and the impact on the U.S. economy makes the identification of the terrorists and a plan to stem the spread of their microorganisms the national priority. While such plots are a dime a dozen, Mills's meticulous research, pacing and carefully developed characters make this variation particularly convincing. (Nov.)
