I bought Arnold Lobel's books in hardcover when they first came out. Our children adored the stories and illustrations and they wanted us to read them every night at bedtime. By following along as we read Lobel's and other "I Can Read" books, our children learned to read before they entered school. The stories are definitely designed to facilitate reading skills but they are also engaging, with a focus on friendship, love and behaviour. I cannot recommend these charming books enough.
Now for the negative comments: The Kindle versions are extremely disappointing; the font and illustrations are quite small. One can double tap and increase the font size a little bit, in small sections. This doesn't allow for reading to a child while smoothly running a finger under the words being read, as it would if all of the text on a page was enlarged at once. Running a finger under the text is a significant step in teaching a child to read while using "I Can Read" books, so this particular "double tap" method defeats that purpose.
In addition, the illustrations don't seem as vibrant as in the hardcover books and they can't be enlarged. The publisher did a real disservice to both the author and the readers by the poor job they did in transferring the books into digital format.
Even with my dislike for the way in which the publisher digitalized this book, it is still a very worthwhile purchase. It's message is timeless and the stories and illustrations are sure to appeal to both it's target audience and to the adults reading it to them.
