Ace Tucker is a man who was raised in outer space and taught how to be human by a Russian cyborg chimpanzee. Ace earns a living as a rock-and-roll roadie and cargo hauler for the greatest band in the galaxy, Mustache Supernova. His world is turned upside down the night he meets Elvis Presley, the very not-dead King of Rock ‘n’ Roll. When Ace saves Elvis from an alien assassin he must travel to Memphis, Tennessee to restore Presley’s health. But things are not what they seem at Elvis’s pastoral home, Graceland. There, Ace makes a discovery that has the power to shape the future (and potentially undo the past).
