The Botanist's Apprentice

I love Powell's writing. They can fit so much into such short stories without it reading as rushed or crammed.
This taked place in a kind of Harry Potter world where people go to school for magic with different types and subjects. The main character is a college graduate who specialises in botany but wants to focus on “dangerous” plants - like carnivorous, poisonous, or noxious plants - and turns up at a renowned collector's door for an apprenticeship. The collector wasn't expecting him however and had a bad experience with an apprentice in the past. He's charmed by the student though so they start a trial period. One of the plants in his collection is a carnivorous plant that gives off pheromones to lure people in. Halfway through the story, this takes on the popular fanfiction trope of Sex Pollen and gets steamy but it read as inevitable rather than unexpected or unnecessary. It also leads both characters to have a breakthrough in their research with a bonus relationship so not a bad result.
All that and more in under 100 pages. I look forward to see more of this world in the next book in the series.
