The difference with self-publishing plays out in the details that commit you. We own them.

Own ISBNs

Legal deposit

Each title is filed with the French National Library, as the law requires of a publisher.

Distribution

Amazon KDP distribution (paperback, hardcover, Kindle), and soon IngramSpark and booksellers.

Careful production

Art direction, cover, layout, ebook and audiobook. An object we're proud of.
