These aren’t as old but the catcher in the rye and Daphne du maurier are easier to understand

I haven’t read many of these books or authors but I have heard amazing things about these. Books by Colleen Hoover( not my thing but well liked) Emily Henry, Taylor Jenkins Reid ( four of the books are connected) Brandon sanderson, Penelope Douglas, Christina Lauren, Fredrick Balkman, Sally Rooney And talia hibbert. Crazy rich Asians, the night circus, project Hail Mary, Eleanor opliphant is completely fine, The kiss quotient, and the love hypothesis. This is all I could think of at the moment. I hope one of these recommendations are something you’d enjoy
