I used this book to self teach myself attic Greek. It is heavily focused on being able to read large chunks of Greek text as quickly as possible. Here's how the book is laid out:
Alphabet, pitch, relative pronouns, 1st and 2nd declension nouns, and active and passive voices are all covered in the introduction and 1st chapter.
Primary texts (with plenty of notes) are given at the end of each chapter after grammar and constructed examples are given.
By Chapter 5, demonstrative pronouns, the future, aorist, and imperfect tense are covered, and the 3rd declension
By chapter 10, all forms of the pronoun have been given and all 6 principle parts, as well as adjectives and participles.
The final 4 chapters covers moods, contract, and -mi verbs.
Maybe it's hard to subjectively rate this , but I really like the way this is laid out. It's very bottom heavy, drilling you extensively on the parts of Greek you have to memorize and then adding in more subtleties as you work your way through the book. When you are 2/3 the way through the book, you can recognize the voice and tense of almost every verb form and get a general gist of what's being said if you have a dictionary handy. I was able to read Xenophon and the New Testament without much trouble and less-successfully navigate The Apology by chapter 10.
I give it less than 4 stars because necessary information is hidden on C.A.E. Luchsnig's website in the form of study guides. The chapter on participles was not well written and I had to use a different textbook to make sense of them. I also wish that there was an answer key provided to some exercises since i used this for self studying.
I'd recommend this for someone whose primary interest lies in broadly reading Greek texts and not so much focusing on specific parts of the grammar. It was a great introduction to the Greek language for me goals.
