I did like this in the beginning. I didn't even mind that it was slow. Very slow. My problem is that it is a very long book, but not a lot of action. At one point I genuinely gasped out loud when one of the divers mistakes a zombie for one of his teammates. Unfortunately, not much else happens. They make a lot of poor decisions. Really, chapter 57 is when I got angry at the sheer stupidity of characters and their decision making.
Why? Why? Why in the world would you take a special item with you? Why would you take an engagement ring down on this type of dive with you? And why in the world would you go back for it? And how in the world did you even find it?! When they said they were going down to find him, I couldn't believe it! Why, why? But also, why did they keep going back down there even before that!? And I did it like the ending, at all. I didn't like how they decided to keep it secret? Why? That's not exactly going to keep people away from it.
I didn't hate it and I loved the idea of water zombies! No thank you.
