TITLE: I need help with the name of a book series
POST: As a kid I started reading a book series, but I need your help in remembering what it is called.
I was about "magicians" in a post apocalyptic world, who searched city ruins for, what is now, modern technology.  However they lost most knowledge of the tech in this great catasptrophy.  These magicians were identified by an earring the wore with a blue ball.  I remember it started off with some street rat sneaking into a mage's house and getting caught and the mage taking him under his wing after creating some voodoo doll to threaten the boy, then dismantling it.  Any help would be appreciated.
TL;DR: Is it something he needs to know about me being bisexual? When would you guys think it is really necessary? What are you guys looking for to mean?
TL;DR: Im bisexual, want to tell boyfriend, want him to know i'm bisexual. When do you guys think it(whether losses or not) is the right time to do it?
