began wring the book because i was a journalist, it was my natural instinct to dig into his story andearnt happened to him and how head fallen so far so fast. thugh the process of writing the book, i ordered his autopsy. that's how i learned it was heroin. >> my goodness. that must have been such ahock to your family. >> it was earth shattering. it was the kind of thing we thought wou never happen to us. a lot of filies feel that way. this is something tt just would ner touch their family. it's very stigmatized and something so unimanable that could happen to somebody that you love, it's shocking when it happens. >> you wrote the book to help learn more about your brother but also deal with your grief. >> y, writing the book was very difficult because i started writing it very shortly after he passed away. so, i was very much in the throes of grief. much of the book is very raw because of that. but i also, as i started to write morebout my brother, i became interested in the fact ts is happening to so many other families. so i started talking to other peoe. hearing their stories as well.
