So, Peter the Wolf has been live on Smashwords for roughly a week or so, but I'm letting the secret out because someone already bought a copy today. I've uploaded the file with Amazon's KDP app, and the ebook should be live there tomorrow.
It's also live on Lulu, in case you wanted to get a print copy. Not sure how long it will take for the print edition to show up on Amazon, but it should be soon-ish.
