Awful formatting, terrible editing, stilted flow, and just overall messy writing.
First, the proofreader isn't doing his/her job. The format made it difficult to understand who was talking. You're supposed to separate dialogue by the speaker. Instead, there were full paragraphs that would go back and forth between characters, and it took me having to reread it to be sure who was speaking. There were several times when the wrong word was used or even the wrong character was being referenced. I.E. towards the end of the book, a chapter from Sandra's POV has her freaking out that Matt has the address to "Sandra's house" when it should've read "Meadow's".
And then... So! Many! Exclamation! Points! Oh my!! I don't mind the punctuation, but it was used repeatedly when it wasn't necessary and it became distracting and annoying.
The overall writing style - it didn't flow very well and a lot of the language was forced and unnatural. I get that the author is male and writing most of the book from a female perspective, but I felt like the constant references to Meadow putting on makeup, checking her hair, being afraid to go out in public without being perfect, etc, weren't being used as a genuine character trait but more to convince us that he knows what he's talking about.
And for the story. The H/h know each other for literally, 24 hours, before they're separated for most of the book. And half of those hours, they hated each other. I know they had a deep connection for that one day, but they don't reunite until almost the very end of the book. Other than sexual attraction and a little knowledge of each other, I had a hard time believing that they were actually in love. At least they have pornographic sex??
