Chapter 1: An Unexpected Shock

Long ago, in North America, as the Earth was emerging from the Ice Age. A boy: by the name of Kenai was just out-and-about hunting; when, he spotted...a ship. Heading right for an ice berg-sized glacier. "Watch out!" he shouted, at the ship. But it was too late, hesitantly Kenai ran to get his brothers, Denahi, and Sitka. Who were hunting not too far away; "Hurry!"
"What is it, Kenai?"
"A...a....ship....about to crash...into an...iceberg," Kenai said, breathing heavily. "Come on...I'll show...you"

What was a boat doing in the middle of the Ice Age anyway and do they meet anyone on it?
