Our ebooks are compatible with most ereaders, smartphones, and tablets. Buying a digital copy through our shop gives you access to a DRM-free MOBI and EPUB copy of the book you purchased. MOBI files can be transferred to Amazon Kindle devices, while EPUB is compatible with other ereaders like Kobo’s.

For information on how to move files to your ereader, please refer to its user manual.

Why are Nyx Publishing ebooks DRM-free?

DRM stands for Digital Rights Management, software that prevents ebooks from being shared between people. We believe DRM provides more hindrance than security. Additionally, DRM software is very expensive. We simply hope that our readers will consider buying a copy of our books whenever they are able to, rather than downloading a copy illegally.

Why am I being charged for shipping while ordering a ebook?

We have been made aware of a bug where occasionally, customers find a shipping fee in their basket while trying to purchase an ebook. We believe this might be because of cookies stored improperly by the customer’s browser. Try adding the digital product to your cart in an Incognito tab (Ctrl + Shift + P on Firefox, Ctrl + Shift + N on Chrome). If the problem persists, please contact us through our contact form and we will help you as soon as possible.
