Query: A badly written book!

The author came across as a rather selfish and arrogant person, totally self involved. There were enough problems up there on Mt. Everest without Gammelgaard throwing temper tantrums because Scott Fischer wanted her to summit with oxygen. She frequently drew conclusions about other's thoughts and motivations without any basis for these judgements. The writing was boring, choppy, and unedited for grammar. Hopefully, Gammelgaard did get around to paying Mountain Madness the balance of what she owed them. She tried to convince us that she did in fact pay in full. Not true. Frankly, the woman has difficulty in relating the facts with truthfulness. I could never recommend a book this poorly written. She didn't really write about mountain climbing. She wrote more about love of self. Her own self, that is.
