One of my favorite books is the Dragon Slayers Academy.
It is about a boy named Wiglaf who is going to Pinwick village for a festival with his mean family. While he was walking to Pinwick, he reads a note, which was on the message tree. It was about DSA, the Dragon Slaying Academy! Wiglaf wanted to go really bad but he had to get his dad's consent. His dad asked everyone in his family except Wiglaf if they wanted to go to DSA. In the end, Wiglaf's dad thought Wiglaf was worthless in the cabbage fields (because he was so scrawny) so he decided Wiglaf could go. Wiglaf was so happy. He didn't think at all about the trouble waiting for him along the way to DSA.
