The user wants a free PDF review of his books. But wait, using PDFs for free distribution might involve copyright issues. I should consider that. First, I should check if there's any official free PDF distribution of his books. From what I know, Marathi authors often have their works available in public libraries or through publishers' websites, but for free PDFs, it's a bit different. Also, some of his works might be older and in the public domain, but I'm not sure. I need to be careful not to recommend pirated copies.
