Finally! A YA book with an amazing cover AND amazing writing. 
 As with all the other reviews on this book, I have to say it's really hard to say what this book is about. There are so many things. It was creepy and touching and loyal and mysterious and paranormal and CREEPY. 
 Ruby and Chloe are as close as sisters can get--or so Chloe thinks. Throughout the book, I really didn't like Ruby at all. I thought she was a liar, a manipulator, bossy, stuck-up, and was really pretty rude to everyone--including Chloe. But Chloe was loyal to her always. Even when she was doing things Ruby specifically told her not to do, she wanted to confess, to make sure her sister wasn't mad at her. 
 I found it hard to connect to Chloe at the beginning because everything she was and felt was all Ruby. It was almost as if Chloe didn't exist without Ruby. And when I finished, I honestly think that was the author's intent. 
 What I loved best about this book was the creeptastic atmosphere. It was intriguing and mysterious, and you never quite knew what was real and what wasn't. You could almost just imagine whatever you wanted, and it could be the truth. 
 The writing was spectacular. I loved it so much. I was so relieved to finally be reading good writing again. The last several YA books I've read have been so awful, I wanted to chuck them into Ruby and Chloe's reservoir, and let the people of Olive take them to their lost city with them, never to be seen above sea level again! 
 My recommendation would be to first go to Nova Ren Suma's site and read the first 76 pages she has up to see if you would be interested. This is a very different story than any I've read--especially in YA. I guarantee it's a fantastic read, but it's not going to be everyone's taste. There is no love story--unless you count the sisterly love. I know I'm not usually one to read a story without one, but I made an exception for this and I'm happy I did!
