Gutwein is a high school student in Phoenix and he started Hoops for Hope. If you're unfamiliar with that, it's the group that raises money for children in Africa. Basically, you take 1,000 free throws in a row and people sponsor you and that money goes to Africa.
Africa's been devastated by the AIDS epidemic, but also by poverty. In the book, there are some statistics. 1.3 billion people worldwide live in poverty, living on less than $1 per day. I live paycheck to paycheck, but according to a global income calculator website, I am one of the richest 4% in the world.
Most of this book is how Gutwein started Hoops for Hope--he saw a video about a young girl (a girl his age, in fact) in Africa, who lived in a small hut with her great-grandmother (her parents and other relatives died of AIDS). He knew he wanted to make a difference, but he didn't know how. After asking family and friends (and prayer), he decided to start Hoops for Hope and use his passion for basketball to make a difference.
But the rest of this book is how the rest of us can do the same--find our passion and use it to make a difference in the world. At the end of each chapter, there's some scripture and also questions that you can answer to help you determine exactly how to make a difference.
It's written for teenagers, so the language is very simple and accessible. I'd recommend this to teenagers, and hopefully this will help everyone want to make a difference. :)
