Whoa. I don't even know what happened in this unique scrapbook of a mystery. It reminded me a little bit of Black and White, a little bit of Griffin & Sabine: An Extraordinary Correspondence, and a little bit of the movie Black Swan (not in the scary sense, just in the sense of "what the HECK is going on?"). Intriguing and unusual. Has anyone tried the app??? 
 "Reading Chopsticks is like watching people kiss in the street: it's private, it's beautiful, it's lonely, it's wild, it's secret, it's everywhere and you can't look away." --Daniel Handler 
 Incidentally, the illustrator, Rodrigo Corral, is the creative director at FSG and has designed a lot of recognizable covers, such as Super Sad True Love Story, The Brief Wondrous Life of Oscar Wao, The Marriage Plot, and A Million Little Pieces.
