Frank Norris 
Octopus [PDF ebook] 
A Story of California

At first glance, wheat farming may not appear to be a scintillating topic for a novel, but in the hands of renowned social realist Frank Norris, this seemingly quotidian activity is transformed into a fascinating analysis of the economic factors that spurred the expansion into the western United States. The first novel in a planned trilogy that Norris never completed, The Octopus: A Story of California is an enlightening and gratifying read.
