I'm currently reading an Aiden Bates book, but I also love Ann-Katrin Byrde, L.C. Davis, Susi Hawke, and Leta Blake's omegaverse. I prefer non-shifter but shifter is growing on me.
I'm also a massive fan of the likes of Garrett Leigh, Roan Parrish, Santino Hassell, Heidi Cullinan, Rhys Ford, Zaya Feli, Megan Derr, C.S. Pacat, Eresse, etc.
There is great smutty filth out there which still has an intriguing plot and characters...you just need to find it. I think, two years into hardcore (no pun intended) reading of this stuff, I'm finally settled into a groove where I have a steady stream of decent stuff to read. It's a bit of a sub-sect that you have to ingratiate yourself into, but once you're there, you find the gold. And when you support the authors you love, there are opportunities that you wouldn't get in big mainstream literature...like the opportunity to get ARC copies. And I've just this minute finished beta reading a story for the first time ever, which was a wonderful opportunity.
