After the Pronoun shutdown I have moved my first book to the following new links in these online platforms:

KOBO
https://www.kobo.com/es/en/ebook/sell...

GOOGLE PLAY
https://play.google.com/store/books/d...

ITUNES
https://itunes.apple.com/us/book/sell...?

B & N
https://www.barnesandnoble.com/w/sell...

The Amazon link remains the same:

In Amazon you can also find the paperback edition.
