Picked this book up from Amazon when it showed up in my recommendations. Great read. The author's passion (obsession?) with understanding the insects trout eat shows through on every page. The detailed photography of the insects is incredible. Book is structured around an annual cycle of hatches, so the flow reads like a story, but packs in a lot of technical information along the way. One of the best flyfishing books I've bought in a long time.
