One Piece (Omnibus Edition), Vol. 20

Join Monkey D. Luffy and his swashbuckling crew in their search for the ultimate treasure, the One Piece.
As a child, Monkey D. Luffy dreamed of becoming King of the Pirates. But his life changed when he accidentally ate the Gum-Gum Fruit, an enchanted Devil Fruit that gave him the ability to stretch like rubber. Its only drawback? He’ll never be able to swim again—a serious handicap for an aspiring sea dog! Years later, Luffy sets off on his quest to find the “One Piece,” said to be the greatest treasure in the world…
Young Luffy’s buccaneering adventures build to a climax as he fights relentlessly to save his brother Ace, who’s slated for execution by the World Government. When powerful pirate Whitebeard steps into the fray it seems like things might start going Luffy’s way...until the Navy blasts back, and it turns out Luffy’s battle has just begun.
