In the middle of Angel Factory

Now I am in the middle of angel factory, somewhat. The book is getting very intense and awkward. Encrypted files on his parents computer reveal that he was adopted. Later the person who decoded them dies in a car accident. And now for my prediction, the people I thought were angels are angels and are training Thomas to be a good person. But not in the way I thought. They are sterile aliens that are made to look like humans and sent to earth to stop it from destroying itself. But its not bad that my prediction didn't turn out the way I wanted it to, predictable books are boring. So far the book is great, and all I'm waiting for is what comes next and the importance of the title, Angel Factory :)
