Overall, this book was really good (obviously, I gave it 4/5 stars). At first, it was a little hard to get into. You are thrust into the world of the Gladers just like Thomas, where all the words and terms are really confusing. After a while, you figure out the meaning of the words and how they are used, just like Thomas. It provided a really cool authentic feeling that you are feeling what the character is feeling that I haven't experienced in many books before.
The book really picks up about a quarter of the way through. I couldn't put it down for long. It's an amazing mystery trying to figure out what the maze is all about and how everyone got there. It's full of twists and turns which, mixed with the really short chapters, just make you want to keep reading. There are a lot of action scenes that are very well described (to where my heart pounds just from reading it).
It's a great book (one of my favorite dystopian books so far if I must say) and I can't wait to read the second one :)
