I really enjoyed this look at Johnstown industry and the stories woven within. The author tells the story in an fairly gripping manner. Some of the dialogue between the individuals telling the stories seems a bit contrived, but overall it was well done. The city has an amazing (ignored) history and after reading this, you really start to wonder how the area would be different had that man-made disaster in 1889 not happened. I also liked how the author intertwined other local stories in the text, such as the Lost Boys of the Alleghenies and how Ebensburg became the Cambria County seat.
This was very dry and didn't keep my attention well. If it hadn't been chosen by my book club, I never would have finished it. The last third was a little better, but the titular "conspiracy" got very little coverage compared to the history of the Cambria Iron Company.
Great review on how Johnstown came to prominence as first an iron and later steel manufacturer. Nice to read the parallel 'growing up' of Carnegie and then actual members of the Cambria Works. Author definitely has an axe to sharpen against Carnegie, but it is not too much of a leap to see how he made his fortune throughout his life.
