A story in both English and Spanish so it can help children speaking both language. That is well done. But what is truly amazing with this book is the fact that it has some cardboard that you can lift, which is nothing new for children book, but it the first time I saw a publisher provide a good alternative to that in a ebook. Too often this is just doesn't appear in ebook and the book become irrelevant but here it truly well done, not perfect, but by far, but far, the best attempt at it I ever seen so good job!!
