What to say...? I did enjoy this book, but there are some pretty big flaws. The FL definitely has a golden finger. Everything she does is wildly successful, and you find out that her father, known as The Alchemist for his ability to earn money, was grooming her to be his successor alchemist. Ok, setting aside the ridiculous nickname...the author really set up the Federation to be pretty backwards when it comes to many aspects of business and living in general, yet at the same time they are a paradise and everyone there is super nice. There is a lack of nuance - what I got was that the Empire is avaricious, powerful, and takes advantage of everyone, San Luenne is money grubbing, and the Federation is amazing. I also think that there was some basic business sense lacking in the writer, and that they forgot some of their own details when it was convenient to the story.
For example, Bertine's own home country, San Luenne, is said to have been very poor about 80 years ago (at one point it said 8 years, but I'm going to assume that was a typo). They had only salt and seafood as exportable products, very little fertile land, and terrible weather. People frequently committed suicide by throwing themselves into the sea because of food shortages. Never mind that if you have a regular, abundant supply of seafood, food shortages shouldn't be an issue - the fact that you can't sell the products does not mean you cannot eat it. They became a wealthy nation when they focused on tourism, becoming a destination for wealthy people from the Empire. But....if their weather is so terrible, how do they support tourism during those times? If they don't have saleable goods, what do tourists buy? However, that was in Bertine's explanation when she was visiting the Hinterlands. If you go back to the beginning of the novel, it says that her nation has year-round temperate climate, very mild weather that attracts tourists.
Not to mention that the royal family (especially the queen) sounds like they are greedy and dumb. Why on earth should they feel threatened by the marquess because he's good at business? How is being wealthy a problem when he's also building wealth for the royal family? Apparently despite his great wealth and power, the royal family can force him to marry a woman of their choosing. Again with a logic breakdown when it came to Luca's family being destroyed by the queen - look, a wealthy merchant/noble isn't going to go bankrupt because a rumor goes around that he's bankrupt and investors withdraw midway from his project. First of all, if the project is already underway, his investors are already committed by contract. Second, if he's that great a businessman, his investors aren't going to believe a rumor that can easily be disproved - they want to make money too, and they'll lose money by withdrawing. Third, why wouldn't he simply ask for backing from Bertine's super rich father, particularly as their families were considering an alliance through marriage? Also, if her dad is super rich, why is 1000 gold coins considered a sum that could bankrupt him? After only a few months, Bertine has already amassed that much in "savings" for the Federation by dabbling in a few deals. This does not lead me to think gold coins are all that valuable.
Then it comes to wheat. The farmers are just selling their wheat for super cheap to the Empire. She tells them that wheat has risen 6-fold in the Empire, and Kurt realizes that he's been cheated as he's only received 3-fold increase. Ok...but have expenses in the Federation also increased 6-fold? Is 3-fold still a fair price in the Federation? Does no one in the Federation buy their wheat, thus setting a price? And fruit. You are telling me that a country that is super abundant in fruit has never learned or even considered preserving that fruit by canning, making jam, or drying it? REALLY? The best they can do is feed the excess to their livestock? Jam already exists, and this never occurred to them? And why does she need to send glass jars and sugar to them? In all of the Hinterlands, they don't have sugar or glass jars?? It's like it's set up so that Bertine is this genius and savior, but...all I can think is that they are kinda dumb to have not seen this really obvious thing.
I'm unclear about Bertine's family. Early on it mentions an older brother, and at some point her stepmom references that the marquess doted on his "only daughter." However, the maid remembers that at some point when Bertine was ill, the stepmother asked the maid to take care of her young daughter
