[Q]: This book was a wellspring of information for me as a newly diagnosed type 2 diabetic. Getting off the cycle of being told to eat complex carbs, seeing my blood glucose spike from doing just what I was told, and getting medications increased again and again, I read what Dr. Bernstein said with interest. After trying his recommendations I can say with no reservations that this book may have saved my life! I highly recommend it to anyone who has pre-diabetes or diabetes and hope that the general medical community opens their eyes. After only one day of this diet my blood glucose readings were close to normal, and continue to stay there, with less medication. My energy levels are high and I have felt better than I have in a long long time. Kudos to you Dr. Bernstein, for daring to say the truth! I recommend both his books and also Dr. Atkins Diabetes Revolution to anyone who wants to learn about diabetes and diet.
[A]: Positive


[Q]: This book is so unrealistic that it spoils all the fun, super killers like Temple Gault (a clone for the Satan Incarnate known as Hannibal Lecter) are more silly than super. I found all the other character two dimensional and all the "intrigue" regarding super computers insulting to my intelligence. Has Cornwell done better? I don't know and, after reading this, am in no big hurry to find out.
[A]: Negative


[Q]: Nathaniel Hawthorne's "The Scarlet Letter" is a vivid (and accurate) portayal of life in Puritan New England. The prejudices, superstitions and institutions of the society are expressed so well that contemporary readers, who have little knowledge of New England's history, are able to feel the oppression and religious pressures that were common in that society. Indeed, this work is comparable (if not superior) to Arthur Miller's Crucible.
[A]:
Positive
