Forgive me if someone has already posted on this, but I just discovered that there's a kid/teen version of Susan Cain's book on introversion, called Quiet Power: The Secret Strengths of Introverts. I loved the adult version of the book and was happily surprised to see this kid version on the summer reading list that my son just brought home from school. So cool of his school to assign it. I'm sure a lot of gifted kids could benefit from reading it.
