Wow! Did Shellie really just say "Flying Trapeze School"? That's pretty dang amazing.
Along that vein, let me recommend "Water for Elephants" by Sara Gruen. I may have mentioned it here before, but it's a great novel. I'm not sure how the movie adaptation is going to play out, but I'm curious to see it. It was such a vivid and romantic book. You can't go too wrong with a summery carnival/circus-y movie, can you? It has that Twilight vampire boy in it for better or worse.
