From a June 15 review in The Washington Post:
The suspense of “The Overton Window” comes largely from wondering when the thrills will begin. There's the obligatory prologue murder, but then the pulse of this novel flatlines. In place of thrills, we get entire chapters in which characters lecture on the rightness of their viewpoints. A moment of cliche action erupts when a New York City taxi with Noah inside jumps a curb and nearly hits a hot dog stand. Later an atomic bomb goes off, but the mushroom cloud settles without so much as a dusty throat for anyone.
The danger of books like this is that radical readers may take the story's fiction for fact, or interpret the fiction -- which Beck encourages -- as a reflection of a reality that they must fend off by any means necessary. “The Overton Window” risks falling into the tradition of other anti-government novels such as “The Turner Diaries” by William L. Pierce, which became a handbook of extremists and inspired Timothy McVeigh to blow up the Alfred P. Murrah Federal Building in Oklahoma City in 1995.
