Be warned, they still have Gateways listed before the Haunted Air, which is incorrect.
The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. ... The piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.
~ Howard Phillips Lovecraft
I've only read the first two repair man jack books and the adversary cycle. I'm really looking forward to getting some of the other books though, because I think I've overloaded myself with the characters. I read them all immediately after another, so I want to take a break and read some of the other stuff, and then get back into it. The only problem is that they're so hard to put down!
