Dead Set by Richard Kadrey

After the death of her father, Zoe and her mother struggle to move on and make ends meet. The only escape Zoe has from her now dreary life is in her dreams, where she often spends hours with her 'brother' Valentine. When Zoe stumbles into the strange local record store, she's offered a chance to see her deceased father once again through a mysterious machine. But, of course, everything has a price. Though she's warned by Valentine to stay away, Zoe's need to be with her lost father leads her into a world more dangerous than she could have ever dreamed.
