When a peaceful protest leaves thousands dead and injured protesters, lying practically on the White House lawn, the country’s many law agencies are forced into uneasy co-operation. Carter, an officer of the law who has to hide his badge as part of his job, needs a place to start looking. Intelligence reports from overseas give him a lead on a score of terrorist organizations. One name though, leads him to an unlikely place and an unlikely source. A reclusive academic, hiding in Montana claims she has an answer—and offers not only a proof but explanation. Carter thinks she’s crazy. Yet in the absence of other leads, Carter has to take her story—and her book—at face value.

Because once in a blue moon…a weapon is born.
