A good futuristic, utopia/dystopia psychological thriller. The tone reminded me a lot of Daphne Du Maurier's Rebecca. Very alienating and purposefully vague. It made for good suspense. 
 I liked the underlying Walden/Thoreau theme. Transcendentalism is probably the closest I come to religion and I think it added a lot to the science/nature debate. 
 Annoyingly, I dropped my copy within pages of being finished, so I lost all but one of my "favorite quote" bookmarks. 
 Here's the one I was able to salvage: 
 I decide that sometimes definitions are wrong. Even if they're written in a dictionary. Identities aren't always separate and distinct. Sometimes they are wrapped up with others. Sometimes, for a few minutes, maybe they can even be shared. And if I am ever fortunate enough to return to Mr. Bender's garden, I wonder if the birds will see that piece of him that is wrapped up in me.
