If you're trying to find out whether 'Ruthless Rival' is available as a free PDF, the short, practical reality is this: only if the rights holder has explicitly released it for free. Authors or publishers sometimes put whole books, sample chapters, or short stories up for download on their official sites or through promotions, but most modern titles are still under copyright and not legally free. A safe way to check is to visit the publisher’s site, the author’s official page or newsletter, or major ebook stores that show whether a free edition exists.
I wouldn’t risk downloading random PDFs from file-sharing sites — they often contain malware and are illegal copies, which hurts creators. If cost is a worry, try legitimate alternatives like checking your local library’s digital services (OverDrive, Libby, Hoopla), looking for a discounted ebook edition on stores like Kindle or Kobo, or seeing if a library can get it for you via interlibrary loan. Sometimes authors post freebies for a short time during promotions, so signing up for their newsletter can pay off. Personally, I’d rather find a legit free option than gamble on a sketchy download; fewer surprises and I sleep better at night.
