Isabella Sinclair spent three years shackled to a loveless marriage, playing the perfect Blackwood puppet. But when her billionaire husband Ethan discards her for his scheming ex, the gloves—and her crimson stilettos—come off. Unleashing her hidden identity as the legendary hacker "Scarlet Serpent," Isabella vows to burn every bridge to the Blackwood empire. Yet her plans collide with Alexander Kingsley, a ruthless tycoon whose icy demeanor hides a lethal obsession. He knows her scent, her secrets, and the fire beneath her calm—because he’s the one who marked her skin in a drug-fueled night of vengeance. From auctioning her ex’s mansion to ash, to dominating the cutthroat perfume world where her mother’s legacy whispers of murder, Isabella’s revenge is a masterpiece in the making. But as sparks fly with Alexander and the Blackwoods plot her ruin, she must decide: Is love a weakness or the deadliest weapon of all? A ruthless divorcee. A billionaire’s obsession. A war where perfume bottles hold more power than bullets.
