Edwards is one of my favourite authors, so I knew I was in for a treat when I downloaded this audiobook. The story follows Ethan and his family, as well as Fiona, who moves in next door. When Fiona starts spending time with 12-year-old Rose, we soon realise that Fiona is extremely evil. This book explores parental child relationships, and what it means to be a psychopath. Although there aren’t many twists as such, there is so much great character development and a constant edge of nerviness pervades the story. It was impossible not to race through it and is one of my top reads of the year.
