安娜・札伊雷斯 writes romance with morally-gray-hero: Close Obsession, Angel's Cage.
In Lenkarda, the main Krinar colony on Earth, Mia is completely at Korum’s mercy. With no way to leave and no idea how to operate even the most basic Krinar technology, she has no choice but to trust the K who brought her there—the lover whom she had betrayed. Will he keep his promise to bring her home, or is she destined to be his prisoner forever? Can a human become a part of Krinar society? Does Korum love her, or does he only wish to possess her?
Back in the devil’s lair, I’m at the mercy of a man who fascinates and terrifies me, a tender killer whose obsession with me is growing by the day. Nikolai Molotov is as much my captor as he is my protector, his compound both my safe haven and my gilded cage. If only I could resist his lethally seductive touch… or fight his growing hold on my heart and mind. Because no matter how far I delve into the enigma of his past, I still don’t know the answer to the most crucial question: Just how dangerous is his love for me? Note: This is the conclusion of Nikolai and Chloe’s story.
