Book is really very nice with good printing and good paperquality. It's short still very nice, and this is what makes it a readable book which will not bore you. If you are an avid reader,you can read it within 8-10 hours.
Delivery speed is impressive. But package quality was not good. As due such tight and small packing book was folder from 1 corner. Paperquality is not good. Content is good. That is why giving 4 stars.
