The topic matter - the Dust Bowl - is fascinating. The author's style of writing, however, is not optimal.
The more I read, the more frustrated I became with what I found to be structurally deficient sentences. I also read the book like a soap opera. In other words, one aspect of the plot was stretched into thirty pages when it could've been expressed in three.
Unfortunately, this made for an unenjoyable read. I confess that I skimmed the end of the book because I couldn't bring myself to read another wall of words. That being said, I did enjoy the personal anecdotes interspersed amongst the dense facts.
I dog-eared a particular quote, which I think sums up the tragedy of the Dust Bowl:
"Of all the countries in the world, we Americans have been the greatest destroyers of land of any race of people barbaric or civilized," Bennett (Hugh) said in a speech at the start of the dust storms. What was happening, he said, was "sinister," a symptom of "our stupendous ignorance." (Egan, 2006, p. 125)
