If you haven't already, check out Kingdom of Ice. Great book.
Oh sweet, I just downloaded kindle samples of them. I have such a long reading list now. I've been reading a lot of cold climate doomed stories, so The Lost City of Z might be a nice change of pace
I did read Ice Blink, it was a definite page turner. Good suggestion. My sister gave me In the Kingdom of Ice, it was pretty good if you have an itch for polar exploration stories again.
I'm currently reading High Crimes: the fate of Everest in an age of greed. It's pretty fascinating to see what lengths people go through and how ruthless people are to get to the summit.
After that my reading list includes Fatal North: murder and survival on the first north pole expedition and Sickened: The True Story of a Lost Childhood
