I need book suggestions.

I’m 28, college graduated, applying to residency, have a good vocabulary, but for some reason have never been able to read anything beyond Harry Potter and Percy Jackson, etc. unless we were required to in school. In college, the only thing I read was what I needed to for class – I only watched TV/anime, and ditched reading entirely. I feel like not reading has really atrophied that part of my brain that’s curious and imaginative, and definitely have a harder time staying focus and engaged in certain tasks.

I’d like some suggestions about fantasy, action, mystery (mix of genres welcome) and stuff preferably written in the last 30-40 years. Books that aren’t too hard to follow but still make me think. Slice of life would be nice – I recently watched A Man Called Otto and heard the book is a fun read too.
