Query: I Couldn't Put It Down

This fast-paced political thriller is what most books of this type are not -- written by someone who actually seems to know the worlds of politics and journalism. The voices of all the characters ring true, and from the most despicable to the most alluring I enjoyed meeting all of them. The jolts in the book were true, timed right, and absent the detour to implausibility taken by so many who try their hand at thriller fiction. The frequent asides, stage whispers really, to the reader also worked -- many provoked out loud laughter. All told, I couldn't put it down and hope this is not Mr. McGrory's last foray into political thrillers.
