This book has felt like a comprehensive overview of Ferrari's 1991 Formula 1 season. The book is in three languages (Italian, English & French) and includes interviews with team personnel, summaries of each race, technical details of the cars and race summaries.
The book doesn't give a brilliant picture of the overall 1991 season, I have no idea what happened between Ferrari and the back of the grid from what was provided in the book - but you could guess that from the title.
There are a few minor spelling or punctuation mistakes in the book, I would guess due to the translation.
Overall it's a good book if you are an F1 / Ferrari fan and want to learn more about the sport in 1991.
