If you want a direct take: full, truly free, legal audiobooks for modern titles are rare, and that usually includes 'Afflicted' unless the author or publisher explicitly released it. I’ve checked the usual legal routes that actually work for me and friends: your public
library apps (Libby/OverDrive and Hoopla) are the best first stop. With a library card you can often borrow the full audiobook file for a couple of weeks at no cost, and availability just depends on the library’s license. It’s how I’ve listened to a ton of stuff without paying per book.
Audible sometimes helps too — there’s a 30-day free trial that includes one or two credits you can use for a full audiobook, and Audible Plus offers a rotating catalog of included titles for subscribers. Also check the publisher’s or author’s website and newsletter; some authors
run limited-time promos or give away an audiobook version to newsletter subscribers. YouTube or random uploads occasionally host whole audiobooks, but that’s hit-or-miss for legality and audio quality, so I tend to avoid those.
If 'Afflicted' is older and in the public domain (which is uncommon for recent titles),
LibriVox or Project Gutenberg Mirror projects are options. But realistically, for a contemporary 'Afflicted' the library route or a trial/promo will be the most reliable legal ways I’ve used—worth trying before paying full price.
