Die for You by Lisa Unger
In a smart New York apartment, Isabel Raine is having breakfast with her husband. After her tragic childhood, she has only ever wanted to be loved. And in Marcus Raine she thought she'd found the man she would be with for ever. But when she says goodbye to him that morning, little does she know that within twenty-four hours he'll have gone missing and life as she has known it for the past five years will be fractured beyond repair. But Isabel's nightmare has only just begun. Desperate to unravel the truth behind the lies, she finds herself thrown into the centre of a violent underworld - one driven by betrayal, corruption, deceit and murder. And it seems no one is safe from those who are determined to make sure that the truth never comes to light.
