Hi

I haven't heard of this book. I have many books plus other resources. I am finding the best way is to learn vocabulary in context within phrases which I find memorable. Also repeatedly listening to the same German videos or podcasts until I am confident with the vocabulary and grammar is helping. So I would summarise by saying I have one German grammar book, three YouTube channels I follow, one free course I am just starting and one subscription service I will join. These are linked below.

It is my first time to hear about these Books , but If you enjoyed it , it is cool , Have you tried (Schritte) or (Aspekte neu) or ( Menschen) , It is also based on which Level you are ! .

Good Luck
