Too Many Negative Points...
...to push this to a 3 star book. Let's start with the characters.
They were shallow, whiny, immature, nonsensical individuals that made it impossible to care one whit about them. For instance, when Emery is to make her London debut, the writer says this: "I pulled my long black hair back with a hair comb and threw in some curls. The I did dramatic eye makeup (which my father would have blown a gasket over) and finished with dark-plum lipstick. I was proving to the world that I was a grown woman and capable of making my own choices." Okay, first of all, this demonstrates just how shallow and unlikable these characters are. How is getting dressed up proof of being a capable woman? Second, it shows just how amateurish the writing is.
Next, let's move on to the plot. It's one-dimensional and a little on the repetitive side (Emery balking and fighting against everything, but still determined to prove her worth).
Also, there's the unbelievable moments, as when Constance cuts herself. Noah is telling Emery he feels guilty that he didn't know Constance had been cutting her wrists/thighs for years and he had no idea she'd been doing that. So I'm trying to survive the dialogue when it gets to this point: "How did she get ahold of a knife?" "She used her butter knife. Can you imagine how hard she had to cut to break skin?" Yeah, not! Really? That was the best you could do to get to that point in the book to explain how someone is all bloodied? You can't cut yourself with a butter knife. It would have been more plausible to say she got hold of a razor blade or something.
Then there's the dialogue, which I barely survived, as mentioned. All it does is solidify the immaturity of the characters.
Overall, this is a pass for me.
