I've read everything she's put out since the After series blew up. Her core lane is definitely New Adult romance, zero question. It's all about that intense, messy, often toxic early-20s relationship drama, amplified for maximum emotional impact. Think college settings, rockstar love interests, love-hate dynamics that border on obsession.
But calling it just 'romance' feels a bit thin. There's a strong vein of contemporary fiction in there too—she taps into the social media generation's anxieties, friendship fallouts, and family baggage. The melodrama is dialed up, sure, but the emotional core is very much about navigating young adulthood. I wouldn't peg her for fantasy or mystery, but within her wheelhouse, she's consistent.
Honestly, after the first few After books, I noticed she tries to weave in more mature themes, like mental health in 'The Brightest Star'. Still romance-forward, but with a slightly heavier touch.
