Query: The quest for drugs.

While a little soft on the discussed science, this was a rollicking good adventure story. There was a lot of action to keep you intrigued, a little plea for environmental awareness and just a smattering of love interest. The descriptions of the amazon was galvanizing and allow great visual stimulation. While the plot had enough holes in it to drain pasta, it still provided an enjoyable read.
