Terms of Sale

Buying a book gives you a personal, non-transferable licence to read it on your own devices. Lending a copy to one friend is fine; posting the file publicly is not.

Files are delivered as DRM-free PDF and EPUB immediately after payment. If a download link fails, email us and we will send a fresh one.

Refunds are available within thirty days, no explanation required. If the book did not serve you, you should not pay for it.

Quoting passages in reviews, sermons, essays or classes is encouraged, with attribution.
