In 2025, the SenLinYu fantasy novel "Alchemised," which began as "Harry Potter" fan fiction, became a bestseller after being traditionally published; its movie rights were sold for over $3M.

Many believe the risk is worth the reward, though the legality remains murky. (Some users may experience a paywall.)

Modern fan fiction exists in a legal gray area

JRR Tolkien believed fantasy literature was an entirely different world

JRR Tolkien redefined fantasy for a new generation

Tolkien's debut novel, 1937's "The Hobbit," was aimed at young adults, yet it felt far more serious than the whimsical tales of Lewis Carroll or L. Frank Baum.
