Does anyone know where all our missiles are at any one time? Could one be taken and used to blackmail the President into changing policy? Aaron's experience in foreign affairs, nuclear security, and high-level Washington and international politics brings authoritative insight to the answers he proposes in this remarkable first novel. He captures not only the petty bickering but also the high stakes power games of politicos. His portraits of an all too human U.S. president and his advisors, and their Russian counterparts, are remarkable. And his skillful attention to detail makes the search ``for a disturbed young man . . . who has in his hands the power to set off a chain reaction of events that may engulf the earth in a nuclear war'' believable and scary. A political thriller on a par with the best of the genreaccomplished, polished, exciting, notable. Literary Guild alternate. Jean B. Palmer, Phillips Acad. Lib., Andover, Mass.
