If you have no idea what I'm taking about, this is my post all about my new novel Cat's Call.
Secondly, the book is DRM free, so you should be able to view it on multiple devices. The file type is .awz ... but I changed mine to .prc (mobi pocket) because that's what it really is and it uploaded onto my BeBook fine.
I'm looking in to offering it in other formats, but haven't made any decisions as yet as to where and when. There are a lot of things to consider.
For anyone interested there's also a handy tool called Calibre - it converts from just about every eBook format to every other and allows you to edit their details, view them and keep them sorted. It's brilliant and it's free. They have a donation button, which I intend to use once I have some money :).
