Suggest me a book with a young female main character and no love interest or romantic plot line

Hello! I am looking for a book with a female main character that doesn’t include any romance within the story (crushes, dating, hookups, etc…). My preferred age range for the MC is 18-25 for relatability purposes, however slightly outside of this is okay! I am a big fan of realistic fiction however I can do a slight bit of fantasy as well. Any suggestions are greatly appreciated <3
