I'm an audio book narrator and they give me codes that I can give out for free audio books that I have produced. All I ask is that you leave a review. If you want a code for any of them, just let me know and I'll DM you one (or more). I have UK and US codes. If you want to hear samples - https://www.louisecooksey.com/audiobooks.html . There's a lot of erotica, but I've done quite a few "cozy mysteries" and "cozy romance", some litRPG, some non-fiction, and horror. Horror is probably my favorite to do, but they don't often want a female voice for that.
