This was very, very good. 
 It's not a dystopia. It's a utopia for actuals, which is pretty sweet. This is a future where disease, war, famine, it's all gone. Conquered, I guess you could say. And for a school project, kids have to experience something from before. 
 Kieran chooses sleep, Maria chooses hormones. Between dreams and teenage angst, the two are brought closer by their experiences. 
 And it's very well done. 
 I'd like if Westerfeld took this concept and kept going with it. But the novella's nice, too :)
