I read Novel Problems for one very good reason: I read the first book in the Sapphire Springs series, Not Just Gal Pals
But, *checks notes* you didn't care for that book.
This is true.
So, why...?
No more questions!
I was wary from the very description of Hannah as a "best-selling fantasy author" and the contents of the book bolstered this concern. She was a best-seller, she was respected, and she was George's (the other MC's) favorite author.
For me, making a character a "great writer" is problematic when the author, almost necessarily, is not. I don't like this in any medium. Many movies have had characters create a diegetic Oscar-worthy film or write an award-winning novel although the movies themselves are typically mediocre and forgettable. The snippets we get of those fanciful works are often melodramatic drivel that is, at best, a caricature of an award-winning story. Why? Because the writer is likely not talented enough to write such material. If they could, they'd be writing that and not the dreck they gave us.
Hannah can't even come up with a less loaded synonym for "romantic" to describe a dinner setting. This "great writer" falls upon an almost nonapplicable "cute" instead of something as simple and appropriate as "charming". Yes, I get that she was nervous but at least make her good at the one thing at which she is supposed to be good.
I'm given to understand that the author is hearing-impaired. Representation, sure. That's great. Then why make this a easily replaceable (which is to say nearly irrelevant) plot device instead of a simple fact of her existence? It serves a similar function as that of sitcom character having a clogged ear canal, so that a "miscommunication" can happen. A sitcom writer uses such tropes because they have 22-minutes to tell the story and its still kind of lazy. So, when a novelist does it, what should it be called? This novel cannot happen without multiple instances of miscommunication.
Hannah also manages to lose her hearing aid in her box of sex toys. How? She asks herself that very question--but really, how? Did it fall out while she was packing and impossibly not notice? Did she wake up and shove all her toys off her nightstand and into a box one day and sweep the hearing aid along with it? Worse, George mistakes the hearing aid for some strange vibrator.
More on Hannah, she supposedly suffers from severe social anxiety, but really, as with the hearing impairment, it's only a problem when it helps to further the plot. Otherwise, it's little more than standard introvert behavior. A person with severe social anxiety shouldn't excel at in-person customer service, such as a barista as Hannah does.
Just so it doesn't seem like I'm picking on Hannah, George (apart from her hearing aid faux pas) pays $160 for two tickets to an outdoor movie. She doesn't wonder why it was so ghastly expensive (it's a fancy dinner, the one Hannah called "cute") and, unlike every other human on Earth, doesn't even ask what movie is being shown.
To compound the stupidity, the movie is Wet Hot American Summer. What? Why? A formal dinner date setting with a fancy meal and they play a mildly raunchy early 2000 comedy. No explanation is given. No one notes it as a humorous juxtaposition. Just a terrible movie choice.
Later they go kayaking, and Hannah suggests she and her ex, Tonya, went kayaking once and Tonya the more experienced kayaker apparently sat in front and paddled alone. Maybe not impossible but also not ideal nor intelligent.
Again, Hannah is a fantasy author but the most fantastical thing is that a program like The Today Show or Good Morning America would care about her identity enough to be eager to interview her. To garner that level of interest, her name would have to rhyme with George R.R. Martin or maybe Stephenie Meyer and it's does not.
There's a lot more to quibble about, but in the end, once again it's a book with minimal stakes and when the moment of confrontation comes, nothing happens. Just reasonable discussion after reasonable discussion. When they aren't diffusing potentially interesting discussions, they worry repeatedly about the same two or three things through the entire novel, even revisiting after it was presumably resolved. Just excruciating.
