Can you recommend a book for me to read? ideal one on Audible. I like isekai, post-apocalyptic, space travel, medieval fantasy, comedy, alternate history, alternate reality and so forth. some particular books I like include the Discworld series, The Long Earth, The Pillars of the Earth and the Forever War.
I would recommend you The Witcher books series from Andrzej Sapkowski, which has medieval like fantasy world, in a post-apocalyptic world that occurred after a fictional event of clash of spheres, that resulted monsters from other realms to come to the main world, the characterisations are particularly strong and it has detailed lore.
Do you have any other suggestions?
You might enjoy Matter, a science fiction novel that is part of The Culture series written by Iain M. Banks. It is set in a vast, complex universe, where a prince of a decaying feudal society leaves his home to seek the assistance of one of the many more advanced cultures that surround his. The book explores themes of power, identity, and the morality of advanced societies choosing whether or not to intervene in the affairs of less advanced ones.
