I've just submitted files to amazon's search inside facility and, if I've got it right, you'll soon be able to read part of The Girl on the Swing on amazon uk and .com.
I don't fully understand how it's organised, having been sent 2 diffrerent sets of invitations (well, 3 actually, but 2 were identical) that seem to lead to the same seller central site. Taking no chances, I responded to both.
It's noticeable that, while amazon.com feels secure and established and automatically linked to the kindle ereader store, by contrast, amazon uk is the poor cousin, lagging behind. Even if, for tax reasons, they have to be run as separate companies, I'm surprised at the lack of interchange of information, which could surely be shared with a simple tick box signature from the customer. An author currently has to repeat everything such as their author page on each site.
But maybe that is changing.
While amazon uk seems to be in a state of constant change and beta testing, if it develops in the way the US store has, with links to e books and a more developed forum, then it could revolutionise publishing for independent authors in UK.
No wonder publishers are worried!
