A new book has a single fundamental element to be learned by the child (such as a single letter of the alphabet, or a single number, or a single color) on the front cover. The internal pages bear images associated with the element, such as words that are spelled with the letter, or images of products that have the color. Magnetically-attracting elements are included in both the spine of the book and a flap that is attached to a fore-edge side of one of the covers. These elements allow the books to be linked side-by-side. A collection of books can be offered as a set, with a separate book for substantially each of the letters of the alphabet. A child can link the books together to spell words.
