The case of the Dysterdal Avalanche has been closed, but police officer Mira Lind just cannot let it go. There are too many things that don't add up, and she is determined to find out what actually happened. But to do that, she needs someone who knows the area like the back of his hand, a man who was there the night of the disaster.

Stian Nyberg cannot believe his ears when the tiny woman tells him she thinks the tourists he left to die might still be alive. If there is any chance she is right and he can make up for that night where his best friend died, then he will take it.

The only member of the Dal Vakt not recently mated, Vedlun, is drawn to the human couple he is supposed to be keeping from Heimli. As both seem eager to help him relieve his frustrations, he is finding it hard to do his job, though not for lack of trying.

But with people comes technology and this time, as history repeats itself, Heimli's worst fears are realised. As helicopters swarm and hearts are broken, is there anything Mira can do to right her wrongs and save the Hidden Folk?
