Since finding decent Beatles slash isn't always that easy, I feel compelled to rec these two Beatles stories I recently discovered and very much enjoyed reading:
The First Year (John/Paul) by candle_beck is set in the early days when John and Paul first met, and George joined the group.
Dear Kings, after the final two episodes have aired I'm going to analyze you to death. Now, though, I'm just going to love you like prophetic butterflies love a future king. ♥
