This book is nothing but frustrating. Serene is awful. She spends over half of the book treating Etienne like absolute crap and for the most ridiculous reason. I found her personality to be quite different from the first and while she's still “rough” and curses and dresses in her own way and what not, I found her to be very whiny. I also found that she made up all these issues in her own mind, caused a bunch of drama over them and then turned around and blamed other people for her own stupidity. 
I loved the beginning with her trying to get back in time, but that part of the book was so short, and then I was left with all of the nonsense surrounding serene and Etienne. 

Don't even get me started on all this other woman crap. It was bad enough in the first one with Will, but having Scarlett around all the time and having them throw it in her face constantly is absolutely brutal. 

I hate a miscommunication trope more than anything, and this was pretty much that, except there just wasn't any communication rather than a miscommunication. I struggled with this one.
