/lit/ - Literature

I want to read a fictional book where the main character is abducted by aliens (preferably in the traditional sense: UFOs) and taken to experience an interstellar society. Not a documentary in which the author claims it happened to him.

Or alternately, a fictional book where either in the beginning or prologue: aliens have destroyed or incinerated Earth, forcing remaining humans to live in the shadows somewhere. Something similar to pic related.

I know there has to be something like these out there, please help me out.
