    The first book I highly recommend is a fanfiction featuring Roon, absolutely the pinnacle of One Piece fanfiction. Following its updates felt like experiencing a thrilling adventure firsthand, filled with passionate clashes and touching moments – a must-read for every One Piece fan. The second book is also excellent; while not an unsurpassable masterpiece, it's certainly a heavyweight. Its author's imagination is boundless yet plausible, cleverly unraveling many mysteries of One Piece. Here, there are no purely righteous Marines, nor absolutely evil pirates; only the dreams of vibrant individuals, and those acts of plunder, good or evil, disguised as dreams.
