My name is Amelia Gray. I'm a cemetery restorer who sees ghosts. In order to protect myself from the parasitic nature of the dead, I've always held fast to these rules passed down from my father. But now John Devlin, a haunted police detective, has entered my world and everything is changing.

It started with the discovery of a young woman's brutalised body in an old graveyard I've been hired to restore. The clues to the killer and to his other victims lie in the headstone symbolism that only I can interpret.

John needs my help, but his ghosts shadow his every move, feeding off his warmth, sustaining their presence with his energy. To warn him would be to invite them into my life. I've vowed to keep my distance, but the pull of his magnetism grows ever stronger even as the symbols lead me closer to the killer and to the gossamer veil that separates this world from the next.
