This book was originally meant as a stand alone, but has grown into a series. I cannot say how it thrills me that there is more. However, this book in of itself is simply wonderful. It asks you to think about what defines humanity. It calls into account things like the value of a human life. Plus, it makes you wonder what would be lost if emotions were less. Being a rather emotional person, I found it fascinating to think about what I would be if I felt less, and acted less.
