The Seraph’s Sin. The Devil's Gentlemen, #6

Mira, a powerful witch of the Boundary Woods, discovers an unconscious seraph-Azeriel, a fallen angel marked by rebellion and forbidden grace. Against all instinct, she shelters him, weaving her magic into his fractured wings, igniting a bond of power, desire, and danger. But their connection draws the attention of Heaven itself. A messenger offers Azeriel redemption, on one impossible condition: he must kill Mira.
Torn between obedience and love, he refuses, embracing a dangerous, corrupted grace to protect her, risking eternal damnation. As angelic enforcers and infernal hunters converge, Mira and Azeriel uncover hidden truths about the first sin-a secret that could unravel Heaven's lies and shatter the celestial order. Their magic entwines, their desire grows, and the boundary between mortal and divine collapses.
In a storm of shadow, light, and irresistible passion, they must choose: survival or surrender, obedience or love. For in a world ruled by divine law, love is the ultimate sin-and sometimes the only salvation. Dark, emotional, and seductive, The Seraph's Sin is a gothic fantasy romance of forbidden love, magic, and defiance.
