Serena Dela Cruz never thought her biggest problem in life would be getting lost on jeepney rides and accidentally entering the wrong place. Lutang, tatanga-tanga minsan, pero matalino sa oras ng klase at kung kinakailangan. She only wanted a quiet, ordinary life... until one wrong turn brought her face-to-face with the shadows of the underworld. Adrian Vitale, the cold and untouchable heir of a powerful mafia family, was never supposed to cross paths with her. His world runs on rules, danger, and blood. Hers is full of missed buses, random daydreams, and a heart that never learned to fear. But fate has a cruel way of binding two opposite souls together. When Serena accidentally stumbles into his world, she becomes a target. And the only way to keep her alive is to chain her to him-whether she likes it or not. Now, trapped between Blood and desire, Serena must learn to survive the dangers of Adrian's world... and the danger of falling for him.
