The 12 best science fiction books of 2025

From drowned worlds to virtual utopias via deep space, wild ideas abound in Emily H. Wilson's picks for her favourite sci-fi reads of the year So: what were the best works of science fiction published this year? I will start with two new books that aren't actually new, but have only just been published in English. First up is Ice by Jacek Dukaj, originally published to great acclaim in Poland all the way back in 2007. It is an alternative history set in Europe in the early 1920s. A terrible winter grips the land, and the cause of it may be something very alien.
