3.5I'm not really sure what I was expecting from Pyxis, but I was pleasantly surprised. My largest complaint about Pyxis was the lack of information, and a few of Corinne's choices (which made me want to smack her upside the head a bit).Pyxis is a relatively short book that yes, ended on a cliffhanger, but I was suitably entertained enough to be interested in picking up the next book in the series.Though I would have liked more background information about the Pyxis and various roles, I felt that it was a pretty unique concept, and uniqueness is always a valued commodity in YA books these days.Pyxis was a free download from Amazon I picked up on March 6, 2012.
