On Shanghai, an isolated island of neon and bloodshed, she falls into the world of vice like a butterfly with broken wings. Her former husband’s sinister cage, her secret lover’s bloody protection, and her first love’s journey across the ocean collide in a three-way struggle that tightens beneath the rain. When gunfire flashes in a sapphire tie pin and tears still mark the soup dumplings, she finally understands in the morning light of a church in the foreign concession: some love is honey wrapped around poison, while some affection is a lighthouse hidden among reefs. After the chaos of war settles, a single edelweiss quietly pierces the frozen earth.
