Prospect Park West by Amy Sohn.
I actually didn't finish it. I really didn't love it. I sort of felt like I was hanging out with someone who name-dropped constantly. It wasn't horrible and from the book reviews I read some people absolutely loved it. I just wasn't one of them.
A SIDE NOTE: There is a character that is loosely based (and I hope really loosely) on Jennifer Connelly. If I were her I would be PISSED.
As to an unrelated matter, thanks to everyone for their budget tips! They are awesome. You guys are great.
