[EX Q]: Stories from central americal often seem surreal. How could it be that people so rich can live in such close proximity to those so poor? How could people motivated by such high principals commit such barbaric acts of violence? Insulated and liberal in America we so much want to empatize with the poor when in fact we have so much in common with the rich. I found this book so very compelling in that it provided much empathy for all sides of this conflict. One could not demonize any party. Instead I watched helplessly as the events unfolded and greived each needless loss. I recommend this book for your soul as your heart needs the exercise.
[EX A]: Positive

[EX Q]: This is nothing new from Gail Howard, or at all. These wheeling systems can be worked out mathematically, without paying for this book. There are also lots of websites that offer number generators and wheeling system explanations for free. If you want it all spelled out for you then buy this book, but if you are willing to do a little mathematical work check out lottery information website like [...].
[EX A]: Negative

[EX Q]: One of the worst novels I have ever read. Well researched - maybe, poorly written - definately. The plot simply goes nowhere, and the characters are so unrealistic and banal that it is impossible to feel sympathetic toward them. Why the author felt she had to abandon any attempt at subtlety, and write as if the readers were as ignorant as her characters seem to be is beyond me.
[EX A]:
Negative
