Query: Berton's a great story teller

First thing, I ran out of Antarctic books to read. I've read them all. So, naturally, I had to find something else to read. First book I tried about Arctic exploration was Frozen in time. Excellent book. The Arctic was worth a second try. Here comes The Arctic Grail. Fantastic work. Couldn't put the book down. Learning about John Ross, Adolfus Greely, Soloman Andre, Robert McClure, John Rae and so on was a marvelous experience for me. The Artic's history is as fascinating has the Antarctic's.You'll get a fine introduction to the Peary-Frederick A Cook rivalry. However, if you need to deepend your knowledge of that controversy, may I suggest "Cook and Peary, the Polar controversy resolved". Dr Cook is a fellow one has to know.Back to the book at hand, you'll learn that the British Navy...learned absolutly nothing about polar travel and your appreciation of Robert Falcon Scott will sink even lower.5 big stars for Pierre Berton.
