My book for (young) adults 'Find your way with an extra X' is also available as an E-book

The E-book is a little bit different from the printed version

It is better readable because of showing 2 following pages on 1 page

Further on the E-book doesn't have an ISBN-number, what makes that the picture of the back cover (to inform you about the book) is a little bit smaller (see the picture down below)
