I picked this up just for the cover.
It looked so apropos at the Jazz Age Lawn Party!
Upon reading it, at first I was a little taken aback by the 'juvenile' feel to it - it's got a hefty dose of teen romance. At times I felt as if the author's ideas about teen relationships were not very firmly grounded in her time period, and were based instead on modern conventions.
However, as the book went on, I got more into it, and fond myself caring what happened with the characters.
It still suffers from stereotypes, and an oversimplified sense of bad/good.
But if I come across the sequel (it's very much set up for a sequel) I just might pick it up...
