There is nothing in this book that is not in any other literary terms book. However, it's the quality, not quantity (isn't that what they always say? Well, it's true this time). The way that terms are defined makes sense to everyone, not just the avid writer or reader of literature.
For example, look up 'Heroic Couplets' elsewhere and you'll find broad, vague definitions with little or no description. Well, think again when it comes to Mr. Abrams version of interpretation. Also, the way the book is structured is clever in itself. When looking up one definition, it leads to other words that are unknown, thus making full use of the book.
If you have any desire to write or just want a better understanding of what terms are being thrown at you in text, consult this gem. If you don't agree, contact me and I'll refund your money (okay, that was a joke). Wise investment.
