You've likely been reading Jennifer Weiner's books for years, and now she's out with a new novel called "The Griffin Sisters' Greatest Hits." The No. 1 New York Times bestseller is known for her hit novels including "In Her Shoes and "Good In Bed." Her newest book is set in two timelines. In the present day, no one knows why the Griffin sisters' band implodes after they rose to fame in the early 2000's. Jennifer talks to our host Whitney about pop culture, often complex sister relationships, and what research she had to do (including an interview with an American Idol star).
