Anything in that vein that you'd recommend? Books I've enjoyed include The Stand, Atwood's Handmaid's Tale and Oryx & Crake trilogy, Justin Cronin's trilogy which starts with The Twelve... I'll give absolutely anything a go tbh. I loved Auster's In The Country of Last Things too, if that counts.
Also, alternate history novels- any you think are great? And maybe sci fi too- I love Mary Doria Russell's The Sparrow and Children of God and the first book in The Forever War series, for example.
All suggestions will be tried outo. I live to read and I don't consider reading even a book I hate to be wasted time :)
