Query: very disappointing

I thought this looked like a good fantasyesque novel for kids (albeit a HP knockoff), but I was sadly mistaken. There was very little character development -- I didn't really come to care about any of the characters. In addition, there seemed to be so many strings left untied. It didn't make sense why Charlie had to go to a boarding school or how that would benefit him. I also didn't see why he was hailed as this great hero at the end because I couldn't determine anything that he had specifically done that was so great. Overall, not a great read. As a middle school Language Arts/Reading teacher, I know that there is so much amazing children/young adult literature that I certainly won't waste time reading another one of these.
