This story asked me to suspend my disbelief ...and I just couldn't do it. I'm sorry (but not really). 
 I didn't buy that society would ever see "unwinding" as a solution. 
 I didn't buy that no one but teens would have a problem with unwinding. 
 I didn't buy that organ donations would solve all problems. 
 I didn't buy that any parent would sign their kids up for this, unless they were a sociopath. 
 I didn't buy the stork thing either. A giant game of baby hot potato? For real? And this is okay with everyone?? 
 I didn't buy that any of this would stop abortions because not wanting kids -or not knowing what to do with them- is not the only reason people do it. 
 I didn't buy that people would not be cool with abortion but totally fine with offing their offspring if they've been alive for sixteen years. 
 I didn't buy that any kid would consent to dying. 
 I didn't buy that people would believe that you live on with your organs. "This isn't dying." Seriously?!? That was the worst spin doctor attempt in the history of spin doctor attempts. 
 I could go on but I think I made my point and I'm done with this book. 
 This dystopian world is based on the dumbest and most irresponsible adults. Why are the teens the only ones who act and feel human? Clearly teens are more maternal too. It's ridiculous. To me, the thing that makes dystopian books interesting is how it could be a dark future of our current world - it points out our flaws and exaggerates them to send a message. A warning. But this just... there is no way it would ever happen and that deflates the experience of reading it.
