​"Even the darkest monster will burn the world to protect his angel."​In the rain-slicked streets and dark shadows of Istanbul, a brutal war for absolute power rages between the city's most dangerous mafia families.​Açelya Demir is innocent, sharp-witted, and stubborn. She despises the bloody underworld her family rules. But when a shocking betrayal shatters her world, Açelya courageously steps in and sabotages a major illegal operation—directly ruining the plans of Ateş Kılıç, the cold, calculating, and ruthless mafia baron who rules the streets.​Furious that his business has been destroyed, Ateş tracks her down and corners her, threatening to crush her family as retribution. Instead of begging for mercy, Açelya looks into the eyes of the monster and makes a dangerous, unexpected offer: "Take me instead of my family."​Intrigued by her fearlessness, the monster accepts, dragging her into his dark world. Bound by a dangerous fate, a fierce love-hate battle begins—and Ateş will soon realize that this stubborn girl is about to become his ultimate vulnerability.
