This is really a solid book, I'm glad I noticed so many others recently reading it on my update feed or I never would have checked it out. Bancroft came up with something pretty unique here, I'd liken it to an inverted Inferno with a solid dose of Steampunk thrown in for good measure. I also particularly liked the evolution of Tom throughout the novel. Looking forward to see how much further he can push his limits in Arm of the Sphinx.
