Can you have a summary of the book slam dunk by Sharon Robinson?

There seems to be a misunderstanding. There is no book titled "Slam Dunk" by Sharon Robinson.

Perhaps you are thinking of:

* "Slam!: The Life and Times of Jackie Robinson" by Sharon Robinson. This book, published in 2007, is a biography of her father, Jackie Robinson, the first African American player in Major League Baseball.

* A different book about basketball with a similar title.

Could you please clarify the title or author of the book you're looking for? I can then provide you with a summary.
