I had so much fun reading this- it was dramatic and over-the-top but in the best way possible. Like a more upbeat version of The Paradise Problem. Like 2 rich childhood turned enemies pretending to be together to save face- please. Thayer especially- she was so type A I loved her. 
Their high school flash backs were the sweetest.
Was the premise silly at times? Yes. Were some ends left loose at the end (

what happened to Millie? and Bennet's mother?

) Yes. 
But I ate it up especially after the slow af book I read before this.
