Apologies for not including it earlier.
I have read through the PDF and it's a well written campaign with a lot of options. Like Masks of Nyarlathotep it spans the globe and can get your players into trouble all over the place. There are a couple of things that I am indifferent about, (i.e. Mu isn't where the rest of the game literature says it is. There is a good justification for the move in the campaign, but it doesn't excite me) well written, looks to be good fun, and probably a bigger campaign than Masks. I'm looking forward to ordering the hardback when it's available.
