A Hike into Horror
Here's the lead for a great narrative story of a bear attack by the L.A. Times: Note how the writer uses short sentences to convey the drama of the unfolding scene, which instantly hooks readers.

Glacier National Park, Mont. — JOHAN looked up. Jenna was running toward him. She had yelled something, he wasn't sure what. Then he saw it. The open mouth, the tongue, the teeth, the flattened ears. Jenna ran right past him, and it struck him — a flash of fur, two jumps, 400 pounds of lightning.

It was a grizzly, and it had him by his left thigh. His mind started racing — to Jenna, to the trip, to fighting, to escaping. The bear jerked him back and forth like a rag doll, but he remembered no pain, just disbelief. It bit into him again and again, its jaw like a sharp vise stopping at nothing until teeth hit bone. Then came the claws, rising like shiny knife blades, long and stark.
