I thought I'd give a little blog about my book. First of all, the author, Lisa Genova is a doctor and her books always deal with a serious medical condition affecting a person and their family.  In this book the disease is Huntington's Disease which is genetic.  It causes total loss of muscle control, so your ability to keep still, swallow, blink etc is affected.  The symptoms also involve violent mood swings.  So the main character, Joe O'Brien,  is a happily married Boston police officer, Irish Catholic, father of four adult children who is diagnosed with HD in his early 50's.  The novel begins with a background of his daily life as a cop and father in "old Boston." Genova also describes the very different lives of the four children; each of them has a 50% chance of getting the disease. Their dilemma is whether or not they should be tested to find out if they have it.  I believe that knowledge is power and I would definitely find out.  What would you do?
