The Atomic Blood-Stained Bus

Gwen McKenna, a bored journalist, has lost faith in her work and instead spends her time pondering the locations of missing people and attempting to make magic work. When David Lowry goes missing, she seeks out his trail, only to find herself tugged under the surface of the normal world and into a layer inhabited by banished gods, secretive witches and psychotic bus drivers.

This time, she might be in too deep.
