www.veronicamars.comVeronica used to be one of the 09ers, a select group of kids in a stratified town (you're either really rich or you work for the really rich) in California. Then her boyfriend breaks up with her (which is how she got in with the 09ers) and her best friend, Lily, is murdered. Her dad was the sheriff, but got voted out because he went after Lily's family. So he became a private detective, and Veronica works for him after school. But she's also trying to figure out who killed Lily, on the side, and she does some private detectiving at school on the side for friends.
We had to watch an episode of it for my YA class (we integrated TV and film into it, because teens are very multimedia-oriented), and I totally got hooked. It's a very smart show, not your average teen soap. Lots of mystery, kind of edgy (sometimes a little too much for my taste, but usually okay).
I loved it so much I tried to do a paper on it, but I had a hard time seeing all the episodes in order in time to do it, so I ended up writing on anachronisms of girl characters in historical fiction instead. Anyway, highly recommend it.
