American Gods by Neil Gaiman

Released from prison, Shadow finds his world turned upside down. His wife has been killed; a stranger offers him a job and Shadow, with nothing to lose, accepts. But a storm is coming. Beneath the placid surface of everyday life, a war is being fought – and the prize is the very soul of America.

An inspired combination of mythology, adventure, and illusion, American Gods is a dark and kaleidoscopic journey deep into myth and across an America at once eerily familiar and utterly alien. It is, quite simply, a contemporary masterpiece.
