You can find an Amazon link posted on the front page on this site. Like the others, it's a universal link. So, if you live in London, it'll take you to Amazon.co.uk. If you live in Canada, it'll take you to Amazon.ca, etc.
Will there be a paperback version? Yes - eventually.
Will I post it on Itunes, Sony, Kobo, etc? - I haven't decided.
Will this get turned into a comic novel - we'll see, I have a guy reading it now to see if he's interested. I don't want someone to commit to a long project like that unless they are fully on board.
The main series will eventually become a comic series as well. I've been playing with the idea of having multiple artists handle separate chapters/issues. It divides up the amount of work, it gives each character's perspective a different artistic style and it allows for a lot of people to get their names/work out there at the same time. From what I understand, this is how they handle the Judge Dredd comics. It's a good idea in theory (I think), how it handles in practice I'll let you know.
