Hey, maybe you found me in the comments! 
Check out my reading list for awesome Taekook/ BTS fic recommendation. 

Wonder how I rank books, well...

I am an adult (22), so I typically like more mature books that have...
   -smut
   -interesting/ mature characters, themes, message, relationship dynamics
I personally also like...
   - happy ending (rarely read sad books/ending) 
   -mpreg/ABO
   -magic/fantasy elements 
   -any and all kinky sh*t
   -slight angst, some fluff
Grammar is not very important since I find it easy for me to ignore mistakes. 

*S class*
I am VERY selective here. These have important themes, good character development and are written very well. I would read again and definitely recommend.

*A class*
I have read, enjoyed and would probably recommend.
