Enhanced descriptions from Syndetics:

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...

Tower of Power

Inside the perilous sea gates of the so-called Judicial Island, members of Luffy's crew are imprisoned in the Tower of Law, due to stand trial in a highly biased court full of World Government warmongers. Luffy's quest to save his friends seems doomed...until he joins forces with a powerful consortium of shipwrights and street fighters. It's an explosive battle on the courthouse steps for Luffy and his Straw Hat pirates!
