Child 44 by Tom Rob Smith. "Gripping beach read. My husband and I listened to it on CD on a car trip, but didn't finish it on that voyage. I had to go buy a 'real' copy. From Amazon: "If all that Tom Rob Smith had done was to re-create Stalinist Russia, with all its double-speak hypocrisy, he would have written a worthwhile novel. He did so much more than that in Child 44, a frightening, chilling, almost unbelievable horror story about the very worst that Stalin's henchmen could manage."
