I created a digital online version some time ago - but wasn't that impressed with the quality. I've finally got around to creating an e-version with Amazon.
It's just come on line at Who Killed Dave? - Amazon and costs $11.99 AUS and $9.99 US.
I've yet to embrace e-books at home, but see it is a good way forward. Maybe a Kindle Christmas present Trev? How do you feel about paperless reading?
