As the title says, this is just Introduction to Norwegian, but still perfect.
Book is something between school-book and common language book. For understanding e.g. verbs/adverbs/nouns etc. you should read the vocabulary at the end of the chapter, and after that read the story (BTW this is the advice written by the author).
Althought the fact that CDs are hard to use when listening them using the radio, you can use more comfortable way of listening - PC. Among the other things, I like that there are two versions of stories - basic and slower.
