Elowen Lockwood, formidable head of a corporate dynasty, meets a stealthy demise when her deceitful husband slips poison into her medicine. Thinking his coup complete, Asher assumes control, completely unaware that Elowen possesses an identical twin sister, Sierra, a battle-hardened international operative trained to survive hostile combat zones.
Assuming Elowen's wardrobe and aristocratic mannerisms, Sierra infiltrates the penthouse estate to dismantle the conspiracy from within. She turns corporate traitors against each other, gathers forensic proof of the lethal plot, and prepares an explosive reckoning at the family birthday gala to annihilate the murderous widower.
