That is (unfortunately) the only book on language level B1, unfortunately because I started six months ago with Spanish and came across at the beginning of the series and have read and heard all the stories. The stories are entertaining and one learns many words, phrases and - from A2 level then several times. The series is not opened didactically - new words you have to paint itself and look - but I find that rather an advantage. The CDs are profssionell and eingesprochen almost at normal speed - which is also an advantage over other learning materials.
