Starting from complete zero you are still perfectly able to learn basic Swedish with very little effort and in a pleasurable way. Importantly they make it dynamic in terms of "interactive" dialogues, but specially in terms of phrase structure. You get to "play" with the word order when the sentence requires so, and surprisingly with their lead you get to do it naturally! This creates a comfortable zone for you to dear open your mouth and trying express your self instead of being blocked if you don't remember by heart the exact thing you are supposed to say.
Further, the speakers they chose have very pleasant voices and accents, in striking contrast to many of other of these books. I bought so far 5 different audiobooks to learn Swedish. The other four were an irritating waist of time that make you loose interest and courage. This book is clearly pretty expensive, but SO WORTH IT!! :))))
Go for it and enjoy!
