The Monarch by Michelle Davidson Argyle

I loved the book as it made the world of the CIA and DEA real and very grey in morals, good and bad on both sides.  It show as the life of an agent changes as Nick (the good guy) deals with his past memories while trying to protect his family from his past coming back to threaten their lives.  We love to call Michelle "the author with a reality check" because everything in her book is about action and consequence and how our choices WILL affect those around us and out of our reach without intending to.  It did have some language and drew very close to the line on an affair and treatment of a drug lords wife.  It does paint a very real image of what it is like to deal with people that have no value of the lives around them.  Excellent story that held its storyline with very few holes.
