The second Sovereign novella deepens the psychological sci-fi dread with a tether that binds captor and captive ever tighter. For readers who like their darkness cerebral and their tension claustrophobic, expect mind games, shifting power, and a romance that reads like a slow-tightening trap. More unsettling and atmospheric than purely steamy, it rewards fans of morally murky control and the dangerous intimacy of two people chained together in the dark.
