Thoroughly enjoyed this book. Agree with some of the others that the transition to "topside" was to quick, but overall, I fell in love with the characters, and enjoy how they remain true to themselves while still allowing room for emotional growth. I truly enjoyed reading about a strong female lead character (Deuce) whose character was not overwhelmed by a romance. Looking forward to reading more in the series.

This book was WAY rushed. From the setting switch to the events that unfolded, it seemed like a breeze. I did like the characters but not the connections between them. I thought that this novel wasn't the best and I was being very nice to give it 3 stars. Quick read.

I agree with everyone who said that the transition from underground to Topside was too rushed; I felt like something had been left behind. This book was sort of "meh". It was in between being good and being completely awful. The characters are extremely human and the emotions are very real, so that's one thing in Ann Aguirre's favor. The thing that I didn't like about it was the fact that those weird zombie-like creatures--Freaks, Muties, Eaters, whatever we're supposed to call them now--showed up Topside for practically no reason other than shock value. I don't know whether I'm just getting bored with dystopian fiction or if it's just the fact that this book was like, mediocre at best. I do plan on reading the sequel, however.

This started out promising. Then on about page 115, the author abandons the entire society and plot she had set up and changes direction entirely. Everything established up to that point is literally left hanging. At page 115, the book turns into a plotless, meandering novelization of the History Channel's show Life After People, In fact, the author credits that show as part of her "research" for he book. At about page 150, the main characters lose the ability to have a functioning conversation. As a result angst results and is never resolved. This reads very much like fanfiction because the author couldn't follow a plotline through to its conclusion and starts mutliple threads but leaves them hanging with no satisfactory resolution: the fate of the other society they encountered in the tunnels; the budding (and then wilting) relationship between the two main characters; and the potential spoiler relationships. With so many great YA dystopians, like Battle Royale, The Hunger Games, Divergent, and Shattered, and classics like 1984, The Long Walk, The Running Man, It Can't Happen Here and the Handmaid's Tale, I honestly don't know why anyone would waste time reading this.

I’m not sure if I’m just getting burned out on dystopia, but this book didn’t grab me. It was okay, not great but not bad either. For me it felt as if the plot was a bit less complex than a book like Divergent.

There was enough of a good plot to keep me reading but I do agree with many of the other reviewers that the change from underground to topside was too quick. Plus I found the sudden emergence of Freaks topside when none had ever been seen before unbelievable when further north they are rampant. I will read the sequel and I will recommend this book.

I really liked it an i thought part one was amazing. i was hooked. then i got to part two and i thought everything was kind of drab, and what was with fade and tegan!!!!? i hated the end but i am SUPER stoked for the sequel, outpost

This was a great book for a lazy summer day. I finished it in one day. I liked the characters. Familiar feel to Hunger Games, which is something I like, but it wasn't too much like it. Story line keeps you reading and interested and wanting to find out what happens. I was very surprised to see the book change pace at Part Two and go from the enclave to topside. It felt very abrupt. For all the criticism of its plot lines, it was still enjoyable to read.

I thought the story was good, interesting concept that I hadn't yet seen... though it was kind of... twisty. I didn't see a lot of the plot twists coming and the way the characters formed... but it was interesting, and i enjoyed it overall. :D

Alright. Well, for starters, the whole tunnel system idea was interesting to me. But then at some parts it got really confusing as to how things worked in that world. And even though this is only the first book of the series, it seems like the author left out a lot of details that just made me confused and I couldn't fully imagine this world that she'd written. I felt like she was also throwing random bits of twists in the plot - like Stalker, and how he just randomly decided to be nice. I mean, I understand it's about survival, but I found it all just added to my confusion. I was left at the end with a "That's it?!" sort of state of mind when the book ended. Strangely enough, I still felt the need to read more and didn't DISLIKE it at all. I just found parts of it thoroughly confusing and coming up empty and short. Because it was interesting enough for me to want to read the next book, I hope it will better. And of course the bigger reason to want to read the next one would be because I hope more of this new world would be explained and any missing details would be filled too.
