Russkaya Mafiya/Oath Keepers MC is the series that launched Sapphire Knight’s career in 2015. It combines Russian organized crime with outlaw biker culture, following characters who move between both worlds.
The ten books track multiple couples through a web of secrets, loyalty tests, and dangerous attraction. It remains the foundation of Knight’s interconnected dark romance universe.
