The Muster: 3

A film crew has come aboard the Giant of the Seas to make a documentary about the strangest school in the world - cameras in the corridors, consent forms in the mail, a whole year of shipboard life politely, lawfully collected. Mari Vega and the Deck Thirteen Society have learned the difference between being filmed and being seen. But one person in the film's paper office isn't gathering footage. She's building a list: the names and faces of the ship's most hidden families - the ones a court in The Hague is about to call as witnesses - and somewhere, someone is paying, quietly, to make sure those people can never be found. The Society is the best in the world at finding people. This year, to save them, they'll have to prove they can protect a name without ever once hunting the person who carries it. Some counts you keep. This one has to be answered out loud. The Deck Thirteen Society is a fair-play mystery series for readers 12 and up. Book Three.
