I realize this is a random story. But it reminded me of my favorite kinds of books: Series. Everyone is related to everyone else. If you meet a character, it is likely he is going to know someone else somehow. And I have to tell you...I love it.
Paranormal lends itself to series better than anything else, I think. Because why shouldn't the two hundred year old vampire know the one hundred year old Werewolf from fifty years ago in Romania?
Do you have a favorite series and if so what is it? Do you find the Central Casting office brings the characters back to be related to each other over and over?
