Query: poorly written, much content fabricated, a work of fiction

This Cold HeavenI read this book with great anticipation, both because I enjoyed Ehrlich's previous writing and because I was with her during some of the events she discusses related to her Arctic travels. When this book was published, I was surprised and appalled to find the writing was often sloppy, and much material had been fabricated or blatantly "borrowed" from other sources. I don't know if Ehrlich counts on people in the remote places she writes about NOT reading her books, or if she dashed this off in haste. Perhaps she is suffering from literary arrogance. In any case, ethical reporting and nonfiction are not her strengths. In the future, she should stick to fiction and poetry.
