I think the difference is you presumably obtained that book legally before writing the review. In this case the book was pirated (the definitely illegal part), and then used for training (the possibly illegal part, but I suspect this would be deemed fair use).

IMO google and their massive google books DB would have a better leg to stand on here if they trained on that dataset as they owned physical copies of all the books.

I don't think it matters. Your review isn't copyright infringement because you pirated the movie.
