I have been using this book for a while now and have found it a useful tool to get my students speaking. The main class I use it for is actually above the grammar level of the book. We use it as a great review. The students love the songs and are enjoying getting to know the characters. As we discuss the storyline in class they talk about the characters as if they know them. It is well structured and I see could be used as the main text for a course or as a supplement text. The sound files are very high quality and well thought out. The book is helping me teach the students comprehend, listen and respond. I look forward to using it with other classes, different ages and levels.
