The Mystery of Grace by Charles de Lint is a contemporary fantasy novel that tells the story of Altagracia (Grace to her friends).

Grace is a "metal Head", customizing Hot Rods at Sanchez Motorworks, it's not just a job, it's a calling. Then she goes to the Solona Music Hall on the Day of the Dead, and meets John. A match made in heaven, except for the small issue of her not actually being alive.

Charle De Lint manages to mix Native American, Hispanic and Celtic cultures and invoke a fascinating story where heavy metal mixes with the undead, weaving a stunning tale of Love, Death and Hotrods.
