One of the hardest questions I get:
What is your favorite book? or What do you recommend?
The reason I find them so difficult is that there are so many possible answers and it very much depends on my mood, whatever I have read lately and also the person I am talking to.
Nevertheless I have wrecked my brain and tried to come with some recommendations in several of my favorite genres together with some explanation why I think you might like it.
At the same time I return the questions: What is your favorite book, and what would you recommend to me? Please let me know in the comments!
