For all devices running an Android operating system - such as Galaxy tablets and many phones - use the epub file.

Transfer the epub file into the "Books" folder of the device and use the book with whatever reader suits you - but here's a firm recommendation -

Lidia's calligraphy fonts are embedded within the CSS - which means I request but don't demand my fonts be used. If your reader allows it (such as Prestigio - it's free) then when opening my book, click the top menu and select CSS fonts or publisher fonts in the options.

The thank you email will include a message about fonts but if you have any questions - don't hesitate to contact the author.
