Need some advice

Hi everyone! I’m very new to learning German and am looking for recommendations on which textbook or resources would be best for a beginner.
I’m also interested in getting into poetry, literature, dystopian/political fiction, horror, and suspense, but I’m not sure where to start or which authors to look into. I’m open to authors who write across different genres as well.
I’d really appreciate any recommendations, whether it’s a textbook, a particular author, or a book you think is worth reading
