Hi Stumped and welcome to the site.
Eric is a bit of a strange beast as far as the books go as it was originally published by a different publisher to Terry's other books. That other company own the rights and therefore decide what format to publish in. Eric was, originally, an illustrated book - hence the different publisher.
However, a quick look on Amazon.com shows that Eric will be available
for Kindle - although it doesn't look like it is yet.
Look, you've got it all wrong! You don't NEED to follow ME, You don't NEED to follow ANYBODY! You've got to think for your selves! You're ALL individuals!
Yes! We're all individuals!
