50 shades of red

Have you read this book?  It's apparently sweeping the nation and is #1 on the NY Times Best Seller list.  I read it while Bryan and I were in Miami (away from kids).  I finished it in about 48 hours and intentionally left it on the plane for someone else to read.  50 Shades of Grey made me turn 50 shades of red.  Did you read it?  Did you like it?
