Every year Melody Vega and her family go to Glacier National Park to their cabin. Melody's mom died in a car crash when she slid on ice in the car. Her dad is not going on the trip because he has to work. Melody does not want to go on the trip because she is afraid she will miss her Mom too much.
Melody, Pops, and her brother are going to their cabin in Glacier National Park. When they get there they are at a campfire and Pops is telling a storey about when he was 10 and was attacked by an animal. Melody thinks the animal it a grizzly bear, but Pops has quills in his leg. It was a porcupine!
One night after a campfire, Old Slim, a grizzly attacked their cabin. After the attack, Mel, her Aunt Cassie, and Steve, a wildlife scientist, go for a hike to a hotel on top of a mountain. Melody went into the woods behind the hotel and a grizzly came out of her bushes after her. She ran for a tree and climbed as fast as she could. The branch her hand was on fell and she fell with it,
The bear is a foot away after she fell. Mel heard something else in the bushes. It was a porcupine that had big quills like metal spears! The porcupine and the bear get in a fight and Mel had time to escape.
The people learned that the trash behind the hotel was causing the bears to come. The park cleaned up the campgrounds and the trash. The Granite Park Chalet Hotel got a huge new incinerator for the trash. The hotel manager was fired. The rangers patoled the park better. The bear problem went away.
