Enthusiasm by Polly Shulman, found at the library category
This was a fun teen romance that was neat little twist on Jane Austen. Julie's friend Ashleigh is always having these phases, or 'enthusiasms.' Suddenly Ashleigh discovers Jane Austen, and decided to go all out. Julie finally persuades her not to wear long dresses to high school, but agrees to go along to a boys' school dance, where they can meet their Mr. Darcys.
Like I said, it was a fun book. Ashleigh reminds me of several people I know, but fortunately, not quite so obsessed. And just about every reader will spot where the story is going almost from the beginning. The fun is in seeing HOW we get there.
Julie is a good character, with a complicated family, complicated emotions, and I really wanted her to get what she deserved. Recommended for teens or adults.
