There was no information on Goodreads about this book. But I have to say I think I've read this book before but I can't remember when or where. It was just so familiar.
It was the story of tourists that went on a helicopter ride to see the frozen north. There were strange lights in the sky that caused the helicopter to crash and they were trapped in a cave by the lights. If they were outside the cave when the lights came, the lights would kill them. Two of them went insane and one wondered off during a light storm. In the end only 2 of them survive and are rescued.
I gave it 4 out of 5 stars. I enjoyed the book but again I felt like I'd read it before but I still have no idea when or where.
