Read The Terror by Dan Simmons. This is a great mix of horror and history novel, using the expedition as its background.
It is a brilliant novel about Franklin and his expedition: The Discovery of Slowness (Sten Nadolny) It has originally been written in german (Die Entdeckung der Langsamkeit). Very well investigated. Especially John Franklin seemed to have been a very interesting character.
Read the amazon reviews: people start to get philosophical, when they write about this book.
A great weekend read, well worth the time. Maybe I should grab it again, too...
