Who is your most interesting character in the novel and explain why?

Boo Radley.  Here's why:

In my GT language arts class, everyone, including my teacher, always thought that Scout's character represented Harper Lee.  But, at the very end of the book, Boo Radley, after saving Jem and Scout, and killing REL Ewell, goes into his home and never comes out.  Harper Lee, unfortunately never wrote another book after she wrote TKAM, which expressed such a deep and 'saving' message.  Boo, as a character just thinks differently than me and you.  He wants to communicate with the children so much, leaving them gifts like twine and soap-dolls in the nook of the tree, yet he never comes out of his house again as if his work is done.  And, why does the book say "...Boo's Children...?"
