Leads

Summary leads are more straightforward than their counterparts. They contain just enough information to attract the reader.

In contrast, feature leads are more complex. These leads treat the reader like he or she is blindfolded and is walking into a trap. As expected, the reader gets blindsided by the rest of the story.
