American Gods by Neil Gaiman
This is the classic, multi-award winning novel from the 'writer of rare perception and endless imagination' William Gibson. Days before his release from prison, Shadow's wife dies in a car crash. Numbly, he makes his way back home. On the plane he meets the enigmatic Mr Wednesday, who claims to be a refugee from a distant war, a former god and the king of America. Together they embark on a profoundly strange journey across the heart of the USA, whilst all around them a storm of preternatural proportions threatens to break.
