Sylvia day does some amazing stuff. Havent listened to them as audio, but i love her work. The crossfire series are good jumping off points.
The rose by tiffany reisz is available as an audio book and is one of my favourite books ever. Her origonal sinners series is bdsm and gets alot of great revews, so if you can find them as audiobooks theyr definetly worth checking out.
Nicola davidsons “fallen” series are also amazing reads if you like some historical bdsm.
I really like stacy reids “the scandalous diary of lilly layton” for a bit of kink. (Though less of the bondage side)
And katee robert. Stellar author.
“In bed with mr wrong” is a good one. Also love her neon gods series to bits. Loads of good options, lots of different stuff to pick from
Theres a thread around here somewhere of book recommendations. Good place to go hunting for options too as many of the big names will also be in audiobook format (A few options to try)
