If you're looking for a good summer read, this should be on the top of your list: Rules of Civility.
It's a beautifully written novel about New York in the 1930s. The story follows two girls—who live as roommates—on their journey of making life work in this big city (but with much more drama and interest, of course, than just watching how they "make it work"). It's funny to see how all these years later, some things never change in the Big Apple. And never will, I suppose.
(...Keep this on the quiet, and I'm not making any promises, but I heard the author speak last fall and he said there may be a movie deal in the works for this book! All fingers crossed.)
