Originally read in high school and at that time it was just ok for me.  Rereading as a much older person I definitely enjoyed it alot more.  Basically a satire of the 1917 Russia Revolution and rise to power of Stalin.  At the time it was published the US Allies of WWII were friends with Russia/Stalin so it must have been an interesting time for this book.  It is a short book (<150 pages) and a fast read.  Highly recommend as a reread.
