Please note: we are in the process of updating this FAQ!
Original Stark trilogy:
SIN trilogy (can be read entirely as a stand-alone trilogy without the others)
Take My Dare (Jackson/Sylvia Novella)
More Nikki and Damien novels:
Anchor Me (full length novel, includes story elements from all novellas but can be read even if you’ve only read the original Stark Trilogy. Really!)
Indulge Me (novella)
Also, the Stark World series with Wicked Grind, Wicked Dirty, and Wicked Torture is set in the world of Stark International, but those books are stand alones, so you can read any of them in any order, though you may hit a few spoilers about the characters from the main series above 🙂
