Book: Kuulostaa hyvältä Sounds Good

If you already know how to say hello in Finnish, how to read the alphabet  and want to improve your Finnish from that point, this is the book for you. I started reading this book after I read about 7 lessons of "Teach Yourself Finnish" and I'm still reading. 
It has 40 lessons of about 5 pages each. Every lesson starts with a short conversation then there are exercises by which you can make sense of what you have read. The answers to the exercises are provided so the book is great for self study.
There are also companion videos for the conversations which are available on youtube.
