Lorie Ann Grover: "No way, should a girl vote for a woman just because she's a woman, Colleen! Both my girls would be upset to hear that they were expected to do so. Thankfully, they are not of my mother's world, but their own. They have the luxury of looking at issues over gender representation. That said, a hip young feminist blog is The F Bomb. This was recommended by iheartdaily, and it's a fresh voice for teen girls.
Girldrive by Nona Willis Aronowitz and Emma Bee Bernstein is compelling, both the book and blog. Here two young women hit the road and interview women across the country about feminism. Answers are different, current, and colorful.
Those two sources come immediately to mind. Other than that, I think reading broadly through YA lit will bring a great balance. The books of today empower girls to think for themselves and stride forward."
(ETA: Read a NY Magazine Q&A with Nona Aronowitz.)
