I really enjoyed this! Probably one of my favorite YA titles I've read this year, and it's an excellent thriller with horror elements as well. It first caught my attention because it has the most eye-catching, gorgeous, and somewhat unnerving covers of the year. It exceeded my expectations, though. I really loved Sunny, and the exploration of her complicated relationship with Candie. The story moves back and forth between "Now" and four years "Before" to depict how they got to know each other, and how they fell apart amidst the pressures of stardom and the third girl in their group jumping to her death... The horror elements were less prominent than I thought they would be, and the ending was also not all that satisfying, and I'm not thrilled to learn that it's the first book in a series. I would still read something else by this author though! Really enjoyed this.
