用户评价
##独立生活需要付出努力
##It was a relief that Water Claire didn't die, but it was sad that Kira's bind dad and Matty died. Gabriel met his mother, sad and happy things happened. Explanation of what happened is in this book. It proves we would do anything for our loved ones. I really do believe this book is great. Answers we would want from the previous books were answered.
##“一切总是和‘想要’有关。” 对第一部同化社区的补充和另一个视角的刻画，但是这个系列越往后约发展出一种奇幻的色彩，像童话一样打败邪恶的结局，反乌托邦的意图也不明显。
##天下母亲。

##给侄子的书自己也读了一下，我觉得欧美作家很突出的一个优势是注重个体心理描写，那种细腻让你感同身受：这就是一种享受。
##将前三部完美的收束在了一起。这四部整体来看有两个大主题，一方面是对极端政府的控诉，另一方面则是对人性中美好一面的歌颂。最后结尾部分加波战胜恶魔的方式也是用爱来打败邪恶，让人动容。
##所有的线索都汇集在一起，克莱尔的爱与克制，加波对自己过往的探求。埃纳的执着与指导。前两大节都很不错，最后加波的天赋设计以及打败交易大师的方法总感觉欠缺了一些。 14.7万字
##最后交易大师死得有点迷啊……但是四本书最后能整合成一个整体，也是很牛了。
