Amber Patterson longs to live the life of the rich and plots to do just that, by making friends with Jackson Parrish's wife; Daphne. Throughout part 1 there's hints that Amber has a dark history that she is running from, but no light is shed on that until toward the end of the book, which makes part 1 a slow burn (imo).
Part 2 starts off making you almost hate Daphne and how she fell into such a luxurious lifestyle. But then it gets good!
