I like this story because it's gay protagonist is a human being, meaning she was faults and virtues (okay mostly faults).  A lot of her qualities: stubbornness, promiscuity, fear of commitment, emotional distance, etc would be found into a lot young men (or taken as a sign of misogyny, depending on who you ask).  But I like that she is who she is, and she's not sugarcoated as a stereotype.  She's an idiot for wandering out into the desert alone and without water, but she's got balls.
As for the story itself, it was promising, but it felt a bit undeveloped.  In the end we're left with a lot of unanswered questions.  Maeda as a character seems rather one-dimensional, and Cassie remain opaque about her past.  We don't really end up finding out anything substantial about any of the characters, and as a result it's to say it was a good story since it feels like we only got to listen to the first chapter of a novel.
