His Divine Obsession. The Divine Debtors, #2

They escaped a world built on divine obedience. Now they must prove that love can survive without it. Sabrina Emberlock shattered the Covenant Tribunal, freed her sister from an unjust debt, and chose the erased god who once demanded her devotion. Now she and Malakor have entered the Shadow Realm to build something the sanctioned gods cannot permit: a refuge where no vow is permanent, no miracle grants ownership, and every mortal has the right to walk away.
But the realm does not recognize Sabrina as Malakor's equal. Its ancient magic bows to him alone, treating her as an extension of his will rather than a sovereign power in her own right. As Malakor's strength returns, Sabrina's mortal body begins changing beneath the pressure of their bond. Every use of their shared power draws them closer, deepens their sensory connection, and makes it harder to determine where his divinity ends and she begins.
Malakor would surrender his restoration to protect her. Sabrina refuses to let him make that choice alone. When the Nine Sanctioned Gods begin sealing the passages between worlds, Sabrina learns that Faye Galehart, the friend punished for helping her, remains trapped inside the Tribunal's brutal Boiler-Archives. Reaching her will require Sabrina and Malakor to create the impossible: a divine covenant that offers protection without possession and can be revoked without punishment.
If they succeed, they will prove that a mortal can reject a god and remain free. If they fail, Faye will be lost, the Shadow Realm will become a prison, and Sabrina may be consumed by the power meant to make her equal. The gods built their world on obedience. Sabrina and Malakor intend to rebuild it through choice.
