Family Ties (джен)

A boy, ostracized for reasons his family never quite explains. A girl, ostracized for being the new kid in school and having a penchant for reading at recess. Two dentists who see a problem they can fix.
 
This fic contains the somewhat-advertised scene of Albus Dumbledore getting poked in the chest repeatedly.
(part 1 of who knows how many parts. each installation in the series will end such that there aren't too many loose ends hanging if I don't write more. there is no posting schedule regarding future parts.)
