My 14-year-old daughter, Sophie, loves “Pretty Little Liars.” Both the novels by Sara Shepard and the ABC Family show that’s based on them. She follows it all, tracking differences in how the stories unfold, discussing it with her friends. So when Shepard recently published "Crushed" -- the 13th book in the series about four high school girls (Hanna, Spencer, Aria and Emily) and their ongoing battles with a dangerous antagonist known as A -- Sophie jumped at the chance to talk with her. We caught up with the author by phone from suburban Philadelphia, where she was raised and continues to live. Sophie asked the questions, and I took the notes.
The TV show of “Pretty Little Liars” is different than the books. Are you happy with the changes that have been made?
