Heard about this during an NPR (maybe WPR) interview with the author. I can already tell the first-person, meandering narrative is going to annoy me (The author says 'journalists are journalists till they die'- but this makes me want to *head-desk* because I have a degree in journalism, and they beat first-person narrative out of us in the first semester...) Plus, in the first chapter, there is already a lot of 'this can't be confirmed by a scientific expert but...'
... this is why I gave up on journalism.
Still, I LOVE butterflies (I've been to 4 butterfly gardens - including the University of Floria-Gainesville permanent butterfly rainforest at the Natural History Museum - http://www.flmnh.ufl.edu/butterflies/
) , so the premise has me hooked.
