Started out interesting, but soon got confusing. The main character, William Day, is trying to redeem a failed mission to the Artic. On this new expedition, he quickly devolves into a hallucinating mess. The reader doesn't know if he is seeing ghosts, or just descending into madness. For me, the story became hard to follow. This is a soft pick for me, mainly because I am fascinated with the Artic and the people who explore it.
