Came off insensitive, content-wise, in my opinion.
Based on the publication date and the current political and social climate, the plot and some language used were inappropriate. I think that as an author, while reading is a welcome break from reality, to some degree you also have a responsibility to be mindful of the work you publish and how that connects to the world around you, which seemed to be completely ignored here.
Moving on, I just didn't like the plot or characters. Brother's best friend is great when executed properly, which it was not here.
It started as a little embarrassing, Luna was almost pathetically into him, which I could've dealt with, but then when it was revealed that he also liked her. Starting from when she was in middle school and he was graduating high school.
I'll say that once more, he liked her from when she was a child and he was a legal adult. So, immediately, no.
Aside from being creepy as hell and uncomfortable, it was also just unrealistic. I don't care how well they knew each other or how close their families were, if you're eighteen and lusting over a middle schooler, you need professional help. It isn't romantic, it's concerning.
It was disappointing too, because aside from all of the other obvious issues, the beginning of their relationship was actually kinda cute. I was down for it, but then, it just kept reminding me why I was not, in fact, down for any of it.
Don't worry that you'll forget this man's name either, because it was repeated in every single bit of Luna's dialogue. I promise you I will never look at the name "Tony!" the same ever again. Disrespectfully. And the sheer number of exclamation points in Luna's dialogue should be a fined offense.
Next, her dad, brother, and now boyfriend are all basically the same person. And it mentions their similarities several times. Unsettling on a number of levels.
Lastly, a direct quote: "... Like I'm a small child." was said way too much for me not to wonder a bit about the dynamics here... At this point is there some sort of kink at play that I need to know about? Is she two feet tall? Is she the Queen? Is that why she is frequently being carried around?
And unless your name is Dominic Vega, the term of endearment, honey, is not for your lips.
