Icelandic sisters âArâora and âIsafold live in different countries and aren’t on speaking terms, but when their mother loses contact with âIsafold, âArâora reluctantly returns to Iceland to find her sister. But she soon realizes that her sister isn’t avoiding her, she has disappeared, without trace. As she confronts âIsafold’s abusive, drug-dealing boyfriend Bjèorn, and begins to probe her sister’s reclusive neighbours - who have their own reasons for staying out of sight - âArâora is led into an ever-darker web of intrigue and manipulation. Baffled by the conflicting details of her sister’s life, and blinded by the shiveringly bright midnight sun of the Icelandic summer, âArâora enlists the help of police officer Danâiel, as she tries to track her sister’s movements, and begins to tail Bjèorn - but she isn’t the only one watching.
