From first line to published book
Three short guides for nonfiction authors, written by a press that publishes its own books with the same method. No courses to sell, no promises: what we explain to every author, with numbers and sources.
Before You Write a Single Line
What to decide before chapter one, so your nonfiction book has a reader, a shape and an ending.
Write with Rigor
How to handle sources, data and quotations in a nonfiction book so readers can trust every page.
From Manuscript to Book
Editing, design, registration and distribution: the road from finished file to a book in the store, in order and without overpaying.
Get them by email

Who writes them
Christian Duarte, a molecular biologist with postgraduate training in biomedicine and neuroscience, and the founder of Zen Books. He was a university lecturer and researcher until 2023 and has since written and published science-based nonfiction under this imprint.
