You can now buy the Kindle version of To Carry the Horn on Amazon, and the other retailers will clock in as soon as they approve the uploaded files. Got my first customer already! Thank you very much, whoever you are.
UPDATED – I'm live on Barnes & Noble, Kobo, and Smashwords, too. The proof of the trade paperback version arrived yesterday, so as soon as the Library of Congress gets its act together and sends me the CIP (Cataloging in Publication) data for the copyright page, that should become available in about two weeks.
Also got my first review, from a stranger, on Smashwords. 5 stars from a satisfied reader! Whoo-hoo!
