Up the Columbia!
A YA graphic history of the Columbia River Dams
From the blurb:
Rose is in Astoria when she hears about the Columbia River Treaty negotiations, which are going to redistribute resources along the river. Power, water, fish, and protection from floods - who gets what? How do you quantify things like that, anyway?
Join her as she travels up the Columbia, learning the history of the river and the dams that regiment it.
Proceeds will go towards distribution costs, so I can give some of the copies for free to schools, libraries, etc.
