In single standalone book? That’s a bit of challenge. Try Dune book 1, Brandon Sanderson Elantris and Warbreaker, Henryk Sienkiewicz The Knights of the Cross and Trilogy (Trilogy can be read as 3 separate books though, it’s tied more by general topic and historical period than by any plot). Also Martin’s Fire and Blood, it’s finished and the writing style is different than ASoIaF.
