Why we recommend it

Set in a dark dystopian future, this sci-fi submission romance threads ownership, control, and forbidden desire through a bleak, high-stakes world. The tone is intense and oppressive, perfect for readers who crave power imbalance, a possessive master, and a heroine navigating surrender within a brutal protocol. Expect heavy themes and slow-burning heat. A gripping, atmospheric read for fans of dystopian dark romance with a submissive edge.
