Every Day, Characters

There are a lot of characters in Every Day so far.  The main characters in the beginning of the book were Justin and Rhiannon and now the main characters are Leslie and Owen. The main character is present but confusing.  It's the spirit, the one who is constantly someone else.  It doesn't have a name and isn't just one person.  It has its own qualities and traits but has to act like a new person everyday.  When it is in love, everything starts to change.  Each person it interacts with changes his point of view and maybe even a trait.  He got some traits from Justin and now is in a tough situation in Leslie's life with Owen, which also deals with love.  He's learning and loving more and more every day.
