Just Started Reading Maze Runner

I am starting to read the maze runner by James Dashiner. I heard that the movie had come out and I saw the trailer, and it immediately caught my attention. It looked very unpredictable and looked like my kind of book. So far I don't understand the setting, and the author has not fully described what is going on around the character. You don't even know the name of the character yet.

From the trailer I predict that he will be characterized as brave and courageous, and that he may not get along with the people around him.  I am so far confused as to why the author has left him so anonymous. Its hard to make connections between this book and other books, or characters. I am actually really glad I saw the trailer because I have some what of an idea or a prediction considering the book hasen't given me anythings. Although its confusing I really like it, and I cant wait to read more.
