Should we wait for you to bump the thread three times before we respond?
Overall it is a great book, but as bluemoonfalc mentioned above, the one problem with the book is the lack of examples.
There is one brief Samurai stated on page 118, but that's it, each clan has four classes, but no examples for each class.
The section on Nemuranai (Magic Items) is 2.5 pages of how to make them, but no example items.
The Monster section is also very small and what happened to the Tsuno? I haven't seen a single mention of them in the book.
There is virtually no mention of the D20 Rokugan, only the titles listed in the reference section in the back.
For someone familiar with the 1st & 2nd edition L5R, this is a great book and you can grab and play. Your only problem will be "catching up" to the Lotus era of the 3rd edition.
If you started with D20 L5R, you may need to take your time and "unlearn what you have learned". You will especially have to go back and read the L5R parts of the dual stated books again.
If you are starting fresh with this book, you might want to see if you can get some of the previous books to help you fill in the blanks.
