Tom Robb Smith is a brilliant freaking genius. The setting for his thrillers Child 44 and The Secret Speech is post-Stalinist Russia, a world of justified paranoia for everyone, and I mean EVERYONE, from powerless citizens to KGB officers and back again (sometimes within the course of an hour).
Child 44 takes place in a world where the State claims murders don't happen; thus, a serial killer can thrive. Leo Demidov, a former state security officer, puts himself and his loved ones in grave danger just for suggesting there's a killer out there, much less trying to gather evidence and put an end to the crimes. (A confession: I am a bit weak of heart when it comes to stories of children in danger. Child 44, which early on contains a riveting scene of a family near starvation, was almost too much for me. But you'll enjoy the second book more if you read this one first.)
The Secret Speech, which hinges on a real life document by Krushchev apologizing for Russia's past mistakes, is mind-blowingly good. Leo now has infinitely more to lose; you will gasp at the lengths he goes to to protect his family. Honestly, my heart beat so fast during some of these chapters that I had to get up and walk around the room to calm down. Each character is complicated; good and evil people and deeds mix and match throughout. Yes, it's a popcorn book, but a hell of a good one.
