To join in and discuss, I am in the middle of Alive which I suggested as a possible option.
I read Into Thin Air in the past, which I really liked, and then heard about the recent film on the Andes crash. I think it is called Society of the Snow. I started reading this book Alive then became so interested in it, I then watched the recentish film on Netflix before I finished Alive. Still half through Alive. Then I found out about one of the survivor's books and am now reading that. So am hopping about a bit but liking it all.
I find it all fascinating.
For a bit of 'light relief' I am also reading Innocent Traitor (about Lady Jane Grey).
Regarding suggestions, I love Pride and Prejudice - great suggestion. The circus one is good too and Girl with a dragon tattoo.
