*TBT*
The other day I was talking to a friend about a fandom, and then I asked her what other ones she was a part of. Turns out, she only had one. Although she's the future valedictorian of our class, I felt a twinge of sadness for her.  I might only be in the top 10% (due to past experiences they don't tell us our specific rankings anymore), but I live in so many worlds beside this one. So, in no specific order:
Harry Potter
Lord of the Rings
The Selection
Sherlock 
Divergent
Dr. Who
The Lunar Chronicles
Shadowhunters
Gilmore Girls
Pretty Little Liars
Gossip Girl
New Girl
Nerdfighteria
 Everything by John Green
Red Queen
Rainbow Rowel
Glee
The Vampire Diaries 
The Carrie Diaries
