Private eye John Taylor has survived war in the Nightside, but it has left a power vacuum . . . one just begging to be filled.

Welcome to the Nightside, the hidden netherworld in the heart of London, where the human and inhuman go to get their kicks, provided they're willing to pay the price in whatever currency the seller demands.

The recent war has come to an end, but now there is no one in charge, and plenty of ruthless people who will go to absurd lengths to grab that power.

Jeremiah Griffin, one of the last immortal humans, is one, but his plans are obstructed when his granddaughter disappears. It's no surprise when he calls on John Taylor to find her - after all, finding people is what he does - but the job is not as simple as it appears.

And to make matters worse, someone - or some Thing - is blocking Taylor's supernatural gift, so he'll have to work the old-fashioned way . . . and quickly.

Hell to Pay is the seventh title in Simon R. Green's New York Times bestselling Nightside series.
