Snowdrops by AD Miller

I really enjoyed this book - it is a thriller with an exciting plot and some good, well drawn characters - especially the main character, who is also very likeable.  The story is not as dark or gory as a lot of thrillers and although it is slightly predictable it still keeps your interest.  There's an underlying philosophical question about morality if that floats your boat (easy to ignore if not).  I liked the writing which is humorous at times, and I thought the dialogue was particularly good as it was very realistic.  The descriptions of Moscow are excellent and I enjoyed the atmosphere this novel created.  A short novel and definitely worth a read.
