Don't leave me hanging...I need to know where this story is going!

I've really enjoyed what I've read so far! It sounds like the narrator is some sort of small-town stalker obsessed with a former friend who is now famous. I love psychological thrillers, and would love to see where this storyline is heading. I'm curious what was their original falling out was about, and I'm also interested in learning why the book is titled, "The Paper Wasp"! I hope I get the opportunity to learn more.
