Can you put it down? Probably not. The Thrillers, Crime & Mystery Books collection at Somii Books is designed for that feeling of complete absorption — when the world falls away and only the story exists. A flagship collection within our fiction books hub, this range covers every shade of dark and gripping fiction.

From psychological suspense and domestic noir to classic locked-room mysteries and gritty police procedurals, our selection covers the full spectrum of what makes crime and thriller fiction so compulsively readable. The UK has a proud tradition of crime writing, and our range honours that legacy while championing exciting new voices from across the world.

Thriller readers often love the genre-blurring titles that sit between thrillers and adventure books — stories where the stakes are existential and the pacing is relentless. Our historical fiction books range includes plenty of historical mysteries and espionage novels that thriller fans adore, and our fantasy books collection features dark fantasy titles with the same propulsive energy as the best thrillers.

The scariest titles in our collection — books that will genuinely unsettle you — also make us one of the best places in the UK to find outstanding horror-adjacent fiction. Pair these with our BookTok books picks and romance books for a well-rounded fiction reading list.
