I would recommend 'Pride and Prejudice' by Jane Austen. It's a classic that has endured for centuries. The story of Elizabeth Bennet and Mr. Darcy is filled with love, social commentary, and great character development.
I would recommend 'To Kill a Mockingbird' by Harper Lee. It's a classic that deals with themes of racial injustice, morality, and the loss of innocence in the American South. The characters are well - drawn, especially Atticus Finch, a symbol of moral integrity.
I'd recommend 'Attack on Titan' if you like intense action and a complex story. The plot is full of twists and turns that keep you on the edge of your seat.
You could try 'Pride and Prejudice' if you enjoy classic romance. The story is charming and the writing is beautiful. There's a lot of social commentary too.
