Enter realms of dragons, magic, and endless adventure with the Fantasy Books collection at Somii Books. From sweeping multi-book sagas to charming standalone novels, we stock the best fantasy books the UK has to offer — beautifully organised within our fiction books hub alongside every other major fiction subgenre.

Fantasy fiction has never been more popular, and it is easy to see why. The best fantasy book series for adults deliver multi-layered worlds, morally complex characters, and plots that keep you gripped across thousands of pages. Whether you are a longtime fan of classic high fantasy, a newcomer who found the genre through BookTok books, or someone who loves the romantic cross-genre magic of romance books blended with fantasy worldbuilding, our collection has your next read.

Our range spans every shade of the genre — from dark and gritty epic fantasy and cosy magical fiction to romantasy (the fusion of romance and fantasy that has captured UK readers' hearts), and from portal fantasies to secondary-world political intrigue. We stock the best selling fantasy books of all time alongside the most exciting new voices in the genre.

Fantasy fans often also love adventure books for their sense of epic journeys, historical fiction books for their rich worldbuilding, and classic books for the foundational texts that inspired modern fantasy. If you enjoy visual storytelling alongside your fantasy reading, our manga & graphic novels range is full of fantasy titles in illustrated format.
