I just started reading "Til We Have Faces," by C.S. Lewis. It's essentially Lewis's retelling of the Cupid/Psyche Greek myth. Pretty intense so far.
Before that I read The Great Divorce, also by Lewis, which is pretty much the greatest book I've ever read. The level of insight into what makes people tick that that book gave me was incredible. The best way I know to describe it is it's about pride, in all its forms. From vanity, to pity, to conceit, and what it means to truly love despite all of our failings.
Other than that, Inheritance was awesome. I read about a dozen books on pacifism, just war, and justifiable violence for a research paper recently. Nothing too interesting, except Martin Luther King Jr.'s book, "Strength to Love." That was simply amazing. But I don't know if you could really call that literature, as it's more a collection of speeches and sermons than anything. But it reads like a commentary.
