DNF at 100 pages 
 This was, essentially, a yawn-fest. Every time I would pick it up, I would get through 20-30 pages and then I would fall asleep. My eyes were literally tearing up from yawning, guys, this has never happened to me before - at leas not to this extent. Sadly, I was not able to get immersed in this story. 
 The concept was very exciting and the idea of an underwater city and a society that sacrifices itself so that others can survive and live peacefully was more than intriguing and promising. But the writing really dragged this book down to the bottom of the ocean. The pacing was slow, the narrative - redundant and boring, the characters lacked any kind of characteristics that would make me root for them, or even remotely care about their fates. 
 I was very determined to wait it out to see if the plot picks up and if anything exciting happens later, but the first 100 pages didn't offer much to go on, and so I lost hope. And interest. I'm sad that I didn't enjoy this book more, I had such high hopes for it (mainly because of the premise). 
 Read it if you don't mind bland world building, slow pacing and unrelatable characters. The concept is there, but the execution is lacking in many aspects. And for the great premise alone, I am giving it two stars instead of one.
