it shouldn't be that difficult
Edited to add: it turns out that if I had created an account with the publisher there would have been a button to push to send the book direct to my kindle app. So, if I hadn't been too lazy to fill in the form, it wouldn't have been that difficult. Read several chapters last night. Worth the frustrations trying to get it.
I just tried to buy hrj's newest book. Or, rather, it has been paid for, I just can't read it. I decided that there would be some value in buying directly from her publisher. The publisher's web page says that if one buys the e-book in mobi format, and has it sent to an email address which is on one's "Send to Kindle email address" list then it should work. I followed the instructions on that web page to make certain the email address I used in my order is on that list. However, the book isn't showing up in my list of Kindle content on the web page, nor on my phone. I can open the email to which they sent the download link, but when I downloaded it to my phone, even though the email says it will be a "mobi" format ebook, the file name has an .prc extension, and when I try opening the file with Kindle or a pdf reader both tools say it is an unsupported file type. I have tried forwarding that file to the same email address, on the off chance that for Kindle to notice it it needs to be an attachment, not a link in the body of the message, but that didn't help either. I have no idea what I need to do to get Kindle's attention that the book has been purchased. I guess the next step is to try emailing the publisher and see if they can help.
