[EX Q]: I have just spent 5 minutes trying to get this damn printer to print an envelope without mangling it. Wonderful.
[EX A]: Negative

[EX Q]: The plot develops nicely then ends abruptly with an unsatisfying ending. It seems to the reader as if the author had reached her contractual page limit and slapped an ending onto the book. A superhuman villian was terminated too easily. The method of capture was not adequately developed. Several promising themes were not followed up by the author, especially the entriquing possibility that through genetic testing Gault's uncle may have been his father or the reason for the military being interested in the investigation. The author took one of the least interesting possibilites and handled it in a below average formulaic manner
[EX A]: Negative

[EX Q]: Great book, techniqes you can use! I love this book, the moves cause pain, but no injury. I really like section on finger locks. I did not have a problem with this book, the pictures were great. If you are in the martial arts, or looking in to them, GET THE BOOK.
[EX A]:
Positive
