Wednesday, we’re talking to journalist Vanessa Grigoriadis, whose controversial new book looks at sex and sexual violence on college campuses. Grigoriadis interviewed more than 100 students, as well as parents and college administrators, to try to understand how sex, power, and consent work on campus these days. The answer is really complicated with good and terrible sides to the story. There’s also a lot of what she calls the mushy middle. Her book is called Blurred Lines.
