I love this book. I only gave it 4 stars because I haven't finished it yet. It's one of those books that you can read over and over and learn new material each time. Matt Ridley's writing style is very easy to follow and he makes the discoveries of science compelling. It's a well organized piece that will most likely intrigue your friends and family as it makes for great conversation. I'm planning on checking out his other published works as well. Great gift too!
