Yes she was a great writer IMO. I am almost finished reading her book Wishful Drinking right now and got a kick out of it. It's just her talking about her life and stuff, but it's very well written and funny. I plan on reading more after this one.
And for anyone interested, HBO is showing the documentary of the same name this Sunday in honor of the Princess. The OWN network is also showing a rerun of the Oprah show that had her and Debbie Reynolds on it, I think it airs on the fifth. Plus another network I can't remember is showing a marathon of Debbie Reynolds movies. Not sure what channel or when though, you'll have to find it lol
