I haaated that book lol. I agree with all the other recommendations you got here! I would add Sharp Objects by Gillian Flynn. I’m going against the trend here but to me it was even better than Gone Girl. Super creepy (which I love!)

If you want something super fast paced, No Exit by Taylor Adams was one of the most effective popcorn thrillers I read. I was actually on the edge of my seat! It’s not a very character focused narrative, however so depends on what you like.

A book that I adore but never see recommended is White Ivy by Susie Yang. It has the academic vibes (in part), questions of privilege, and “enraged girl in a precarious situation” vibes you might like. I struggle to categorise it…there is a murder/secret but it’s not really a thriller. It’s almost like a dark novel of manners. The main character is unlike able but in a very interesting way I found.

Carol Goodman! I second these recs: Goodman for a more classic thriller, but with emphasis on atmosphere, Tart for what I can best describe as Gothic satire? That book is truly in a class of its own (though I’m biased because it’s one of my favourite books ever). Don’t expect a straightforward mystery, however. Rio was clearly very inspired by Tartt. Some find that a flaw, others a quality. Villains is much more “contained” than Secret History but still not a standard mystery. Both are very character driven, almost like a character study at times. Definitely more psych suspense than thriller on either cases I’d say.
