Austin dipped his paddles in the water and steered the kayak toward two boats anchored about a hundred feet apart, less than a quarter of a mile ahead. The boats carried race officials and press people. Stretched between the boats was a huge red-and-white plastic banner with the word FINISH written on it. Rafted together on the other side of the finish banner was a barge and chartered ferryboat. At the end of the race, the kayaks would be pulled up on the barge and the participants would be treated to lunch aboard the ferry. Austin's father was watching the race in a forty-eight-foot white-hulled powerboat named White Lightning.

Digging his paddle in, Austin was preparing for a sprint to the finish when he noticed a flicker of movement out of the corner of his eye. He turned to his right and saw a tall curved fin cutting through the water in his direction. As he watched, at least twenty more fins popped up behind the first one.

Puget Sound was home to several pods of orcas, who fed on salmon. They had become local mascots, and a big boom to the economy, attracting tourists from all over the world who flocked to Seattle to come out on whale-watch boats or take part in kayak adventures. The killer whales would come right up to the kayaks and often put on a show, breaching partially or jumping clear out of the water. Typically, the orcas would glide harmlessly past, often within a few feet of a kayak, without disturbing it.

When the first fin was about fifty feet away, the orca stood on its tail. Nearly half its twenty-five-foot length was out of the water. Austin stopped paddling to watch. He had seen the maneuver performed before, but it was still an awesome sight. The whale inspecting him was a big bull, probably the leader of the pack, and must have weighed at least seven tons. Moisture glistened on its sleek, black-and-white body.

The whale splashed back into the water, and the fin again moved rapidly in his direction. He expected from experience that at the last second the orca would duck under the kayak. But when it was only a few feet away, the whale again reared up and opened its mouth. The rows of razor-sharp teeth set in the pink mouth were close enough to touch. Austin stared in disbelief. It was as if a beloved circus clown had morphed into a monster. The jaws began to close. Austin jammed the wooden paddle into the creature's maw. There was a loud snap as the teeth closed on the paddle.
