Since the day her son participated in the most devastating high school shooting America has ever seen, I have wanted to sit down with Susan Klebold to ask her the questions we've all wanted to ask—starting with "How did you not see it coming?" and ending with "How did you survive?" Over the years, Susan has politely declined interview requests, but several months ago she finally agreed to break her silence and write about her experience for O. Even now, many questions about Columbine remain. But what Susan writes here adds a chilling new perspective. This is her story. — Oprah
