The scrub want the outside to be true so they can get away from their miserable lives. So, Trella tries to prove him wrong by finding the prophets hidden CD that show the way to the Gateway. But one small mistake leads Trella into a cat and mouse game in order to find the Gateway before the ones in charge destroy her and her friends.
Great book! I saw some of the twist coming before they came. But the ending wasn't what I expected. Throughout the whole book it leaves you guessing what the Outside really is. Trella is a great character, she is an outsider, with not very many friends. You really get to see her character develop as the story continues on. There are a lot of great characters in this book. I could not put the book down, I kept wanting to read it find out what happened to Trella!
This book reminds me alot of the book The City of Embers by Jeanne DuPrau and the book Incarceron by Catherine Fisher. Both books, like Inside out has the characters looking for away out of their isolated world.
