One discarded daughter. Two powerful families. Ten failed experiments. Sloan Hollis Villanueva is a ghost. An elite assassin and underground fighter, she is the secret weapon of the Villanueva empire. But when the burning ruins of Holloway University force the elite Frost family to seek refuge at her school, Sloan's cold world begins to shatter. The Frosts don't recognize her. They don't know that the "troubled" heir is the same twin they left at the orphanage 19 years ago. They don't know that she has spent every day since then learning exactly how to destroy them. But as revenge draws near, a darker truth emerges. Sloan isn't just an abandoned child-she is Asset Zero, a genetically engineered weapon created by a global shadow syndicate. And now, they've sent their newest masterpiece, Nova, to reclaim their property and "delete" the prototype. In a storm of blood, betrayal, and engineered rage, Sloan must decide: Will she be the glass that shatters, or the gale that levels everything in its path? The debt is 500 million. The payment is blood. The storm has finally arrived.
