JapanTimes : GENKI: An Integrated Course in...
You will want to get the workbook as well, since that's where you will be doing all the practice work. Like I said, this book is normally meant to be part of a class curriculum, but the book is explanatory enough that one can learn from it on their own, albeit at a slower pace.
I don't know whether this book you purchased is a dictionary or a textbook, but you can't learn Japanese from a dictionary. It's impossible. You need a textbook... that's why I recommend Genki -- however, there are other ones - perhaps one even in Norwegian, though you'd need to find that yourself.
