Interesting to say the least. The world building was pretty great and totally unique to anything I've read. 
 I don't feel like writing a whole review so I'm just going to randomly spout things off and you'll hopefully get the general picture of what I thought ;P. 
 -The beginnging was a bit slow in my opinion, it seemed like it took forever for things to get moving. 
 -Eldest is an asshole. 
 -Elder is kinda cool, and actually normal despite growing up in the surroundings that he did 
 -Amy, I like her, she seems like a relatable character and it was easy to empathize with her. Also I liked the alternating POV because it not only gave insight into both Amy and Elder but showed more of how they held themselves outside of their heads and what they thought of each other. 
 -I thought the storyline was a bit predictable but worth the read nevertheless. 
 -The feeders are basically like trained animals, I would never want to live like that. 
 -The writing style was okay, nothing awe-inspiring, but average. 
 -Orion seemed like a cool guy (view spoiler)[despite being a sociopath, too bad (hide spoiler)] 
 -Okay, about the end...(view spoiler)[I can't say I didn't see it coming. There was obviously something up with Orion, I'm just ashamed I didn't think of the ear communicator sooner. And the drugging of the feeders was obvious, the reason behind the frozen people's murders was kinda weird and random. And it was extremely random the revealing that Elder unplugged Amy, you'd think that at least a tiny bit in the book there would be some foreshadowing or something of his guilt, but it was kinda just thrown out there after everything else was over, I'm not sure how I feel about that. (hide spoiler)] 
 -But I also kept thinking the whole time that the book was going to end like that movie Pandorum with Dennis Quaid, which is something my mind kept going to while reading this. I'll probably watch it tonight lol 
 -Any way, another thing about the end was at first I was mildly pissed off and confused. No surprise there(seeing as I'm usually confused upon finishing things) but going into this I thought it was a stand alone novel, then I got to the last page and was like "Wait...whaaaa? Where's the rest? There's so many loose ends!" But then I looked it up and apparently it's the first in a trilogy. So all is good my friends. 
 -overall, good and totally worth the read, even if what originally pulled me to the book was the cover, not even the description Lol ;P
