futuristic/ survival= my type of read. im liking it.

I had seen the cover around which drew me in, its very pretty: the colors, the waves with the 2 faces coming out of the waves. from both the title and cover u cant quite tell what the book is about,so i got a mysterious vibe from it. when i read the synopses i knew i had to add it to my wish list bc of the whole futuristic and survival (since cee is stuck in that island) vibe to it. (both are 2 of my favorite genres) the fact that its about 2 sisters also has me interested bc i also have a sister. reading the excerpt so far im liking it, it has that mysterious vibe to it, and it already made me say "wow :o " on a certain scene when shes looking at her reflexion.that certain thing is very interesting and im curious to know why that happened. i like that u follow cees point of view and kaseys. so far the futuristic set up has a few aspects that remind me of other scifi books ive read. wowoow :o this book is very interesting.. i wanna know/read more for sure!!
