Excellent, absolutely necessary if you want to learn French seriously. It is presented and made in a way that is very logical and enjoyable to read. It begins with short stories all written in French, which illustrate a first, second or third person account of an event, and at the same time illustrate the tense that you learn in the chapter. It explains each tense in depth with examples and practice exercises to go over what you just read. At the end of each chapter there is a summarized practice exercise of everything the chapter covered. Includes ALL tenses, times, etc. Very very good book.
