i like fiction books especially heroic or epic writings. they detach you from your world so you can live a life in them, they open your imagination so nothing will be impossible anymore. 

The plots of my favorite books are... the tragic parts i mean those plots that are tangled with sorrow:

in Shahnameh (a persian epic) i like where Sohrab is killed by his father Rostam and the last words of Sohrab.

i like Tolkien works a lot, i love all his writings and among them i like "silmarillion" the most. in my opinion the most beautiful plots in this book are: the battle between fingolfin, the high king of Noldor, and Morgoth. the death of Feanor. and the story of Beren and luthien.

in harry potter books i like the scene in which Snape dies and the memories that he gave to harry. 

the second group of my favorite books are in persian, and they are poetry, i mean there are some poems that i dont get tired of reading, like "Arash the archer" by siyavash kasraee. "eagle" by Dr. natel khanlari, and so on.

   My books do not have "plots".  Non-fiction is what I read.

If the books or novels about plot, detectives, sciences, and magic, perhaps Western styles are much attractive, but contemporary romantic storytelling on novels I prefer to choose Taiwanese drama more sometimes not most of time for learning English, a kind of touching in proceeding a relationship but a little bit unrealistic in our own imagination of when you require many loyal men in reality or anticipate your love is always in return as long as your choice is your wish.

I usually read non-fiction books, mostly biographies, autobiographies, or personal development.

Comparatively, I prefer biographys and novels based on real history incidents to make up fictions.
