I thought I had read more YA recently, but instead I came up with
Gamer Girl c2010

Luna c2006
http://www.amazon.com/Luna-Julie-Anne-Peters/dp/0316011274/ref=sr_1_7?ie=UTF8&qi...

Someone Like You c2004
http://www.amazon.com/Someone-Like-You-Sarah-Dessen/dp/0142401773/ref=sr_1_2?ie=...

All of these have school scenes and take place over most of a school year. All have female protagonists. I guess I'm going to have to bulk up on my YA...
