Ron Thornton

When terrorists plant a bomb on a commercial flight, the passengers aboard the plane must fight to keep the plane in the air and all the passengers alive: the bomb is rigged to detonate whenever the plane dips below 800 feet.

Fenn the Troll hates the Troll pastime of pranking, and is teased so much for it that he runs away. But when a long-suffering park ranger starts capturing the other Trolls, it's up to Fenn to rescue his family and friends.
