Try The Death of Mrs. Westaway by Ruth Ware. Her writing style is similar. The plot is different, but it has a gothic vibe. Wendy Webb and Simone St. James are pretty good authors to check out, too, since you like the slow burn and the haunted feeling of a Gothic book.
I like Gothic horror, so I expected the slow, deliberate pacing. I liked it a lot. I think the author did a great job of using gothic horror as a statement on colonialism, complete with eugenics! At times I was afraid of the mushrooms and the gloom in the same way that the cordyceps mushrooms in The Girl With All The Gifts scared me! It’s like being slowly terrorized. It was very well done.
I would have liked to get to know Catalina better, and the Mexican healer needed a bigger storyline, too. That said, I think Noemi was a well developed, and layered heroine.
I like these lists for the obvious reasons, but the NPR list is always filled with books I wish I liked more than I did. There are some great stories in here, but some of them felt like homework and so I DNF them.
