I would say their are many antagonists throughout this book. I will choose Daniel's dad for this though ,because he is there throughout the whole book. I don't see how Daniel accepts his dad after the way he treats his family. A lot of the things that Daniel speaks of show that his dad has no reason to act the way he does. This could be true ,but also the book is told through the eyes and ears of Daniel. The whole truth might not be told or perhaps lies.
