Hop over to Sierra Magazine, where the wonderful Maren Hunsberger wrote an article about teen reads with an environmental twist. She describes Some Act of Vision as full of "political and environmental intrigue, teen drama, vivid characters, and a splash of romance."
Mayah's Lot, also covered in the article, was a nice discovery, too. It's described as an "environmental justice comic book," and not only is the pdf available for download, but there's a video for kids on the website. What a great inspiration for other middle-school classes.
