This was really well-written, and the mystery and suspense kept me hooked and guessing. I still have questions that are unanswered, but it felt like the ending gave the answers we'd been seeking from the beginning, and these are just hooking me for the next book. I also loved the characters and their interactions felt like real teenagers. Their relationships with each other made me love them even more (

even if Noah seems to have gone off the deep end in the last chapter, I can't wait to see what happens with that

).

This book turned out to be not what I was expecting to read. The story develops in a fine line between sci-fi and fantasy. At any moment, I could see the story tip to one side or the other due to all the mystery surrounding... everything. The last few chapters are the only ones that set a stone into the sci-fi genre, until then, it's just speculative.

I didn't mind being clueless for so long. In a way is what grabs you. You commit to the book and then you want to see it all the way through. Find out what is project Nemesis? Why is Min being murdered and breathing again? And all these questions and many more that came up, kept me turning pages. Although it was slightly annoying seeing the characters curious and decisive to understand what is happening, but then get lost in other dramas and problems instead of looking for answers. I'm used to these kinds of stories having the teens going out to look for answers on their own and only stopping when they find them, but instead, with Min and Noah, they went out to find even more questions and stopped. And this made the story drag a little bit more.

If I wasn't curious to understand what and why is happening, I probably wouldn't enjoy it. The story develops slowly and dedicates a lot of time to the characters. There were a few things (if not everything) that surprised me, but then again that was through to the end of the book when some questions were finally being answered.

The characters are... complicated. I like Min, she has her heart in the right place. But besides her, there isn't any other character. Also, this lack of connection between the reader and the characters only piles up on the slow development. I didn't care that much for their feeling or their thoughts (that sometimes were the same over and over again). I wanted them to do something, to go out, to look for answers. And at times, it seemed very obvious that's what they should be doing, but instead they would get into some drama or trouble or even do nothing.

I was expecting something quicker, something faster, more straight to the point, but instead is a bunch of characters I don't care about, have some terrifying behaviour for teenagers, are too aggressive, and aren't that much adventurous. Although I'm continuing with the series to see where it leads to, and maybe when I have all the answers my opinion might change.
