THEA STILTON AND THE GHOST OF THE SHIPWRECK

There's a haunted shipwreck off Whale Island, and a rare diamond was lost when the ship sank. When the Thea Sisters' biology teacher disappears, the mice have to dive deep into the ocean to find him - and hopefully recover the precious jewel! And just when they think their adventures are over, the five mice are invited to China to search for another lost treasure!
