This is a very carefully written, amazing piece of work and I would recommend it to anyone who wants to keep up with this fascinating issue of cloning science. It is easily accessible to those who have zero knowledge of cloning, but it is also a fun read to those who have had some courses in biotechnology. You will be amazed how many questions you had in the past will be answered in this book. Levine navigates the readers extremely well through the basics of the cloning science to the hot topics including Dolly the Sheep to the recent ethical debate over human cloning. It is also very user-friendly in that he provides a good list of further reading for those who would like to explore more. The notes, glossary as well as index at the back are also extremely helpful for quickly refreshing your memory.
