Ghosts are alive on the island of Nantucket. You can hear them in the wind, and in the creaks of the old homes. They want to be remembered. And, even more, they want to protect what was once theirs. The ghosts seem to have chosen a few local kids to be their messengers - and to help save the island. But in this mystery, the line between those who haunt and those who are haunted is a thin one - and the past and the present must come to terms with one another in order to secure the future.

Thirteen extremely valuable pieces of art have been stolen from one of the most secretive museums in the world. A Vermeer has vanished. A Manet is missing.

Now they've been matched with two new sleuths - Zoomy, a very small boy with very thick glasses, and Early, a girl who treasures words...
