A twisted psychological thriller about the complex relationship between twins

The premise grabbed my attention straight away and sounds like it has the potential to be deviously twisted and full of complications. I love looking in at the relationship between two sisters and that the characters in this book are twins fascinates me. From the start of the first impression the writing is so clear, to the point and the backdrop of luxury and glamorous lifestyles held such appeal as I’m always interested to see how the other half lives. Throw in a few unexpected twists and it sounds like my kind of read with the promise of vicarious travel!
