I spent a long time deciding which version of the paperback books to buy (the adult or children editions). Although the front cover art-work on the adult editions is more attractive (to me, as an adult), the print is terrible in comparison (tiny, blocky font on cheaper/rougher paper), and sadly makes the books feel very cheap. I went for the children's edition, and have not regretted it! The books in this edition are set on good quality paper, with a easy-on-the-eye font, and come in a sturdy flip-top cardboard case. Look no further!
