"Somewhere Here on Earth" - Looking for Tyka Nelson's Book

I'm excited to say that I talked to one of Prince's relatives last month! I won't mention the name for privacy purposes, but the relative let me know that Prince's younger sister and only "full" sibling, Tyka Nelson, wrote a book about her life, "Mama Never Taught Me How to Sing."

That is not a picture of the book. I actually don't know what it looks like; I haven't been able to find it anywhere. In addition to reading books on Prince, I try to read the biographies of those who are--or were--close to him. As you know, I've read Dez Dickerson's book, and I plan to buy Denise "Vanity" Matthews' book.

So, Prince fans, I need your help. Does anyone own Tyka Nelson's book?
