Query: Heavy going - great writing

Be prepared, this is not easy reading. Theroux's writing style is packed full of convoluted and fantastically created sentences that require close attention and rereading. That being said, Theroux is a truly literary writer who dwells in the realm of introspection. His main character, tortured by love and full of misgiving, is led on a not-so merry chase by one of the most devious and conflicted females of literature. A truly remarkable depiction of a pathological love affair gone horribly awry.
