Not often you can read one book which synthesises the disciplines of history, geography, biology and linguisitics, seeking to explain why Europeans colonised The Americas and Africa rather than the other way round, but my summer read has achieved this and more. It is called "Guns, germs and steel" by Jared Diamond.
Next up "Incongito" by David Eagleman, in which his neuroscience studies are used to explore the power of the unconscious mind and even drifts in to areas of moral philosophy.
