A woman's investigation into her sister's death exposes the dark side of a secret life in a gripping novel of power, money, and murder by a Wall Street Journal bestselling author. Sisters Nadia and Cass Brenner are heirs to Ocean House, a decades-old empire that builds superyachts for the rich and powerful: emirs, oligarchs, and titans of industry throughout America and Europe. They're a next-generation success with the design of their soon-to-be-commissioned megayacht for a Chinese billionaire. But the sisters' entrée into the coveted Asian market is tragically cut short when Cass falls from a fortieth-floor hotel balcony. A Singapore detective rules suicide. Nadia's been in the yacht business too long not to be suspicious. Especially when she discovers Cass's involvement in dangerously illicit activities. Pulled into the same web of betrayal, lies, and secrets that trapped her sister, Nadia is on the most perilous mission of her life. Because uncovering the truth behind her sister's death could tear the Brenner family apart--and it just might get her killed. From Seattle to Austria to the South China Sea, Nadia must hold on to the one thing that can keep her safe. It's the Brenner family motto: Trust no one.
