Recently, Amazon has shifted the requirements for its eBooks from the .mobi format previously used for Kindle books to the generic .ePub format. This makes it a lot easier for us, as we don’t have to juggle multiple formats.
As such, we will no longer be uploading the .mobi format for our newly published titles. Kindle users should be able to read the .ePub versions we offer on their devices.
If you purchase a book and encounter difficulties reading it, please feel free to contact us via the contact form and we can provide other formats, including the .mobi format.
