Bellwether

this book stuck with me for years. It taught me the concept of the Bellwether, which is a leader that is not obviously a leader, but influences from within the crowd. Connie Willis didn't write a time travel book this time, but a poor research student is studying trends: what makes things popular, and again, the results are hysterical. This book tends to be fast-moving and breathless, but I still loved it the second time around, and ten years later.
