To be brutally honest, I have to say it is not written in a very gripping fashion - although as a matter or principle I don't like
@MarkH's suggestion about using AI tools to improve it, I fully understand why he has suggested it.
Also, as I mentioned to someone else today, there are already many books on this subject in English. I would suggest considering very carefully whether this book makes an additional contribution to the literature before putting a lot of effort translating it into this language. Unless it makes a highly unique contribution and fills a gap that is not yet covered by the existing literature, you may be better off putting your effort into translating it into a language which does not yet have much literature on the topic.
