Hildur Knútsdóttir recommends

What Feeds Below (2026)
Tatiana Schlote-Bonne
"What Feeds Below hooked me from the very first page and then took me on a wild dive through a world that is as magical and hypnotic as it's dangerous. I loved it and all of its creepy creatures!"

The Girl with a Thousand Faces (2026)
Sunyi Dean
"A visceral, haunting tale of rage, revenge, and forgiveness, set in an irresistibly vivid and mesmerising alternative Hong Kong. I ate it up!"

Wolf Worm (2026)
T Kingfisher
"This kept me up way too late, I literally had to tear myself away. Wolf Worm is hearty, atmospheric, gruesome and funny - and reminded me all over again why T. Kingfisher is one of my all time favourite writers."
