If there was such a thing as chick-lit thriller or dark chick-lit, this would fit solidly into that. I thought it was a thriller, so was a bit baffled by the chick-lit style writing, although the twist at the end moved it solidly in the thriller genre.
This was an impressive debut with well-drawn characters you will love to hate. And hate them you will! Pammie was so despicable that at some points I wanted to shout at her, or tell Emily to walk away. Adam was truly narcissistic and Emily was arrogant and seemed to think she knew best about everything. The ending snuck up on me a little, but I enjoyed this character-drawn exploration of a twisted family with dark secrets and a mother-son relationship.
