Leo, Martin and I have just been finalizing how to divide the first Mirabilis book into eight chapters - or issues, I guess is another way to look at it.
Without any forward planning at all, the whole thing breaks up very nicely into comic-book-sized chunks of around 20-25 pages each, and here are the individual covers.
We got so carried away with the idea of each chapter being a comic book in its own right that we've even added a letters column edited by the chaps at the Royal Mythological Society.
The first issue is already up as a flipbook on the Mirabilis website as a preview of goodies in store. As for the rest of the series - more news very soon!
