Olga Grjasnowa "All Russians Love Birch Trees / Der Russe ist einer, der Birken liebt"
A deeply felt insight what it's like to be a person in their mid-20ies to mid-30ies with a "migration background" in today's (well, 10 years ago) Germany. If you never been asked "but where you are really from", this book will teach you why you should never ask this question. If you did, it will deeply resonate with your experience. You should read it in any case.
