How do you contact an author for questioning on her book?

Well, I went to the lybrary. And I got tons of books. I am currently reading this book called "Embracing Death" "Riding lifes transitions into power and freedom", by Angela Browne-Miller. And I looked her up on wiki, google, etc. I cannot find a way to email her about this book. I want to ask her, how she knows all this stuff if she hasn't even died yet. XD lmao. Because it's about what happens after you die, and I already have my own theories, being an atheist and all... But hers are really out there lol. And she's not dead yet.... Soooo I am HIGHLY curious how she knows these things. Because it's all suppose to be fact. It's not like an opinions book or anything, it's all suppose to be fact. You have to see the book to understand what I mean. But basically the point is, how do I contact this author?
