A classic you've been meaning to get to

[Ramona]

I have so many on my list for this category! Here are the ones I'm thinking about:

Don Quixote

Jane Erye

The Grapes of Wrath

The Sun Also Rises - Hemingway

The Beautiful and the Damned - Fitzgerald

[Stina]

Possibly La Belle et la Bête. Or Stranger in a Strange Land.

[Raúl]

I personally went with Treasure Island. It was fun but I think there are better choices, to be honest.
