I liked this potty training book, but I would recommend having others to read too. This book doesn't talk about going poo-poo and it seems to focus more on being unsure of using it (with a big happy ending). I would use this as a way of introducing the IDEA of using the potty instead of using it to teach HOW to use the potty.

Love! We are just at this stage and my daughter can really relate to the little girl in the story.
