The PDF file contains a large number of external links, many of which are structured as SEO spam, pointing to various PDF files hosted on different domains. One of the embedded URLs, 'http://zephyrhome.com/uploads/1/3/0/6/130639477/130639477.html#percy+jackson+titan%27s+curse+graphic+novel+read+online', suggests a lure related to popular content to attract users. The PDF structure and the mass of external links indicate a link farm or a distribution mechanism for malicious content, likely aiming to redirect users to potentially harmful websites.
