First -let me digress for a moment. The musical "Caberet" used a tawdry nightclub and a doomed romance to convey a dark political reality - that of the danger of Nazi Germany. Now, back to "Water." The novel, "Water," similar to Cabaret," features politics and romance, in order to tell a an salient political story. This story, of course, is not of Nazi Germany, but of the unintentional, but preventable, poisoning of much of Iowa's drinking water.
I really enjoyed exploring Iowa with the protagonist, Freja Folsom. First, like the majority of Americans, she was naively ignorant of the poisoning of America's drinking water by agriculture. So she was a somewhat believable character. I also liked that her character remained realistic through her occasional embracing of casual sex, with her on-again, off-again lover.
The author did a good job of using Freja to demonstrate that there are two sides to every story, even one where it's obvious who the perpetrator is.
Occasionally, though, a few scenes seemed forced, such as when the farmers opened up to her, on their opinions on the interaction between agriculture and drinking water quality.
Overall, this was an easy bedtime read - and the clever chapter titles served to amuse the reader. Perhaps it is my own personal knowledge regarding the issues of water quality that prevented me from naming this as a 'great' book. I'd be curious how others, less knowledgeable on this niche issue, would find it.
