Daddy's Girls by Tasmina Perry

Second Hand 

This is the book beaches were made for. The Balcon sister's are London's paparazzi darlings: Serena, the country's most beautiful actress, Venetia the glamorous designer, Camilla, the rising political star and Cate, the feisty magazine editor. They have wealth, privilege and sizzling sex lives. But money doesn't buy you love. When their aristocratic and tyrannical father, Oswald Balcon is found dead, the finger of suspicion points towards his glamorous daughters and their dazzling lives. Suddenly, we find that beneath the ritzy facade of the Balcon family lies a web of deceit and betrayal that hides a thirty-year-old secret that threatens to destroy them all. From the sun drenched beaches of Mustique to Manhattan's elite society circuit
