i'm reading 2 (well, like 8, going back three years, but...) books at the moment
homo deus (which i believe sam also read), which is a book about anthropology and the future of humans
la belle sauvage, which, admittedly, is kind of for kids - it's the first book of a new trilogy in the setting of the his dark materials trilogy (the northern lights/golden compass, the subtle knife, the amber spyglass)
