** spoiler alert ** 
 McGuire has written a dark, cold, bloody book that's ultimately satisfying, though I wish it had been longer, more developed. Maybe I wanted to follow Sumner all the way to safety; maybe I wanted more from Drax's p.o.v. on the ship (or, rethinking, maybe not...); or maybe I just wanted more of the men, camped on the ice. 
 Although I didn't get a four-star feeling from this, I did appreciate the atmosphere McGuire has created and the tense story he's told. And John Keating does a solid job narrating: his voice has just the right kind of quiet authority and he walks nicely among the different English and Irish accents.
