The truth will unravel everything...

The morning after a glamorous, luxury wedding, you and your best friend go to wake your twenty-four-year-old daughters.

You need to work together to find your daughters, testing your friendship to its limits. And you can’t help but wonder: which girl is the killer and which is the victim?

Such a Nice Girl is, in my opinion a 'Wow' book - another surefire bestseller for Andrea. I couldn't turn the pages fast enough. So many twists and turns! I had no idea who was telling the truth or who was spinning lies. I felt like I was on a roller coaster ride while reading it. Andrea is brilliant at plotting. A fantastic premise, executed flawlessly. I can see it as a movie! * Patricia Gibney *
