Although I waited over 2 weeks to receive "The Compatibility Gene", it was definitely worth the wait. Daniel Davis does a fantastic job at revealing the wonders of the immune system - as I read I was overwhelmed by how influential this part of our genome is in our bodies and my feeling of awe was definitely facilitated by Davis' elegant way with words. He brings the story of the immune system to life with anecdotes about the scientists who have devoted their lives to studying it which are both funny and entertaining while at the same time put into perspective the amount of hard graft and frustration that these people face in their work. I read the book within a few days because it was so well written and entertaining, I'd go as far as to say it was hard to put down at times. I would highly recommend this book to anyone - scientist or non scientist - it is a fabulous example of science being communicated very well.
