Another exciting novel from the spy-master, Daniel Silva. Moscow Rules has our hero Gabriel Allon back in action. This time he's in Moscow where he's brutalized and told not to come back. But Moscow is where he must return to stop one of the most powerful arms dealers in the world from delivering the deadly weapons to al-Qaeda. The twists and turns in this non-stop action thriller were exhausting, but I hope to recover in time to read Silva's next novel.
