The war that almost destroyed the Nightside – that city of eternal darkness hidden deep within London - has finally come to an end, and in its ruinous wake it has left a power vacuum, just waiting to be filled.
Jeremiah Griffin, one of the last immortal humans, is determined to be the one to fill it, but his plans are obstructed when his granddaughter disappears. It's no surprise that he calls on John Taylor to find her - after all, it's what he does - but this time the job is not so easy. Someone - or something - is blocking Taylor's special gift. So this time he's going to have to work the old-fashioned way. And he's going to have work fast, before Griffin loses his heir.
