Title: Five People You Meet In Heaven
Author: Mitch Albom

This book is good because it gave a new perspective on life.

This is a fiction book. My sister recommended this book to me, because it teaches you some important lessons in life. This book is about an 83 year old man who is a maintenance worker named Eddie at an amusement park called Ruby Pier. He has worked there his whole life, despite serving a term in the army during world war 2 which he received a life changing injury in his left knee that left him crippled. The book starts with his death, throughout the book he meets five people who make him relive certain events from his life when he was alive. And while he is living those events each person he meets teaches him a valuable lesson in life that he never realized when he was alive.

Questions
1. Why did Eddie only get to meet five people?
2. Why did Eddie enlist in the army?
3. How come Eddie never left Ruby Pier?
