I dont understand the hype behind this book. High school students would find it very useful, for sure. College students, sensible and mature adults? Newspaper reading. Working professionals, advanced degree holders? Waste of money. If you can comprehend newspaper editorials without much difficulty, then you wont miss this book.I think the writer was confused about who his target audience is. If no one but beginners benefit from this book, then it should have been marketed that way. That being said, this can be a good gift for teenagers. I strongly believe in using logic and reason wherever possible, so I will definitely gift it to my younger cousins.Most adults can safely ignore this book.
