Enjoyable, easy to read book. Great investment, tax and cost saving tips. Useful examples, both good (profits) and bad (losses) taken from experience. Lots of historical facts about stock market history. Well worth the price. I don't feel the book is the only book you'll ever need. Took about 6 to 8 hours to read.
