Sometimes you have to fight fire, with Hellfire.

I didn't have a choice. If I hadn't done what I did, Reaper would've set in motion a chain of events that would've consumed London and everyone in it in unholy, demonic flames. With Levi, Mason, and the Eyes stretched to breaking point, I have to push one more time to try and put an end to the chaos that fell over my life the moment that book made it into my hands, but a visit from a ghost throws a spanner in the works that threatens to send me into madness before I can complete my mission. Worse, if I'm not careful, I could become an even bigger threat to the innocent people around me than Reaper ever could be.

I should've died in those tunnels, but I didn't, and now I'm the only one who can stop Reaper before he sets the world on fire . . . but I'm running out of time.
