Phantom Hourglass is one of the most recent Zelda games, and is currently the only DS game in the series.
Phantom Hourglass is set shortly after the end of The Wind Waker and features the same Link and Tetra. In the beginning of the game, Tetra is kidnapped by the Ghost Ship, and Link falls overboard while attempting to rescue her. He awakens on a strange beach, roused by an energetic fairy named Ciela, who guides him to her Grandpa. Link then sets out on a journey to rescue Tetra from the evil clutches of the Ghost Ship.
