It's 1972. Eddie Edmunds is a rock guitarist in London. He's got an unworldly source for his music, his band Evolution Device is the best there is, and his guitar is beyond compare.
Fame and fortune are not all Eddie had imagined they would be, though. The higher he rises and the more the world worships him for his dark energy, the faster the magic of the music spirals out of control.
It's the insidious power of the black-hearted guitar that is creating a nightmare from Eddie and Lilith's dreams.
Lilith should have the power to help Eddie - after all, she's part of his soul and has been the unworldly source of his music since he was born. But how can she act when the guitar is reaching for Eddie's soul, Eddie is dosing himself with drugs to shut down the magic that has turned against him, and Lilith is losing her hold on her very existence?
