Not a bad read, though not what I had expected. Perhaps I was looking for something more definitive, something that would come closer to answering the big question. Synthetic biology doesn't play as a large a part in the text as I thought it would from the title.
Instead, it's a summary of how different scientists have approached the beginning of life and have attempted to define life. The writing is very easy to follow and is done in such a way that people with no biology or chemistry background should have no trouble following the ideas presented.
