Eek! Yep, I get higher royalties on Dreamspinner sales.
I'm not sure how you get it, Juliana, I just signed into my account there to have a look for you, but as I have an author account it looks different. (Shows me my sales, which looks nice and healthy!) But, if I sign out and look, I can see there's a link at the top of the page that says 'my bookshelf.' Perhaps you can download it from there? I know when I asked if I could give it away in the blog, they said yep, just let them know the person and they'd add it to their bookshelf. So you must be able to get it from there somewhere. Download it and email it to your Kindle. (Which is what I've just done from my author account!)
