Cuddling up to her two dogs on a leather sofa, Iselin Rose Borch looks like any other teenage girl.
But Iselin Rose, 15, survived the Utoya massacre by hiding behind a rock while right-wing extremist Anders Behring Breivik gunned down young people at a summer camp, and says her pets have helped her to cope with the aftermath.
'In the period after Utoya I had a really hard time sleeping,' said Iselin Rose, who was rescued by tourists in a boat.
This photograph of Utoya survivor Iselin Rose Borch was among the collection that won Norwegian photographer Andrea Gjestvang the L'Iris d'Or photographer of the year prize in the 2013 Sony World Photography Awards. Miss Borch is seen with her pet dogs who helped her come to terms with the aftermath of the massacre by Anders Breivik

He then made his way to a summer camp for Labour Youth members on Utoya, where he roamed the island with a gun, mowing down 69 and leaving more than 100 injured.
Last August, he was sent to Ila Prison near Oslo for pre-meditated murder and terrorism to serve a 21-year sentence, which can be extended if he is considered to remain a threat.
Another survivor, Ylva Schwenke, is seen baring her shoulder to show her scars from being shot in the shoulder, stomach and thighs. She survived by hiding in the island's 'love path'.
She said: 'I bear my scars with dignity, because I got them standing for something I believe in.'
