Unless "John Twelve Hawks" is really Grant Morrison, he owes Mr. Morrison a good percentage of the sales of this book. "The Invisibles" (a graphic novel series from the 90's) covered all this territory almost a decade ago. Although not a ''rip-off' of the series, it was definitely influenced by the 'The Invisibles' world. Mr. 'Hawks' hasn't even tried very hard to cover it. The 'Travelers' are the 'Invisibles', both secret societies that have existed for some time and are able to visit other dimensions. The protectors of the 'Travelers' are the 'Harlequins'; a group that assists the 'Invisibles' is called the 'Harlequinade'. Interdimensional beings abound; the bad guys want total control of the populace and are accomplishing it through their influence on government agencies. And so on...I'm not saying not to read the book, just be aware of its origins.
