I'm going to choose to interpret this as 'favorite fanfictions on Wattpad about the Beatles'. :)  Some of my favorite Beatles fanfictions on Wattpad are the following:
-If the Beatles Were by MissMaccaSunshine
-West End Girl (Paul McCartney) by moptopsandyoutubers
-Daddy by @bellaholmes
  You should totally read these books, the authors are all amazing writers and people!! :) (Of course, there are many more good ones besides these, I just wanted to have a top three.)
