This is book 2 of the "Holly Barker" series.

This note contains spoilers for the book.

Holly cracks another huge federal case, this one The Elect (religious nuts) being about to assassinate the president (who was Will Lee at that point) and subvert the military and take over.

She even brings the FBI in fairly early, and manages to negotiate getting to press the murder charges against the bank robbers she cared about (they murdered her fiance the morning of the planned wedding) rather than losing all the suspects to the FBI.

Stone Barrington is a minor character; Stone is in line at the bank with her fiance, and tries to save him but fails.
