Many of my all-time favorite novels have a common (if slightly unsettling) thread: They feature an unreliable narrator at the helm. The term was popularized in the 1960s by the literary critic Wayne C. Booth, but the unreliable narrator herself has been around at least as long as the Wife of Bath in The Canterbury Tales. An unreliable narrator is one who tells a tale with compromised credibility, whether the narrator herself understands that or not. The reader usually finds this out only slowly, as cracks in the narrator's version of events begin to appear. For the reader, figuring out what really did happen is an unending but joyful mystery.
