I bought this book hoping I would find a really COMPLETE tool to help improve my english (not my native language). It took me several days and reading dozens of comments to find this one, that suprisingly has over 600 good reviews! I have found the book lacks of examples of sentences to disambiguate terms. The section for DETERMINERS takes 4 lines to describe and doesn't even bother to mention any of 9 subcategories. ALso the word "ITS" is missing from the Posesive pronouns list! I am not trusting reviews over a book ever again.
