When Calder Pillay travels with his father to a remote village in England, he finds a mix of mazes and mystery - including an unexpected Alexander Calder sculpture in the town square. Calder is strangely drawn to the sculpture, while others in the village have less-than-friendly feelings toward it. Both the boy and the sculpture seem out of place...and then they dissapear!

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. And nobody has any idea where they and the other eleven artworks might be...or who might have stolen them. The Players - Calder, Petra, and Tommy - are no strangers to heists and puzzles. 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...

Where is Early's father? He's not the kind of father who you think would disappear. But he's gone. And he's left a whole lot of trouble behind. As danger closes in, Early, her mom, and her brother have to flee their apartment. With nowhere else to go, they are forced to move into Chicago's shelter system. Once there, Early starts asking questions and looking for answers. There are patterns and rhythms to what's happened, and Early might be the only one who can use them to track him down and make her way out of a very tough place.

Danger is never far from Audra’s family farm in Lithuania. She always avoids the occupying Russian Cossack soldiers, who insist that everyone must become Russian - they have banned Lithuanian books, religion, culture, and even the language. But Audra knows her parents are involved in something secret and perilous. When Cossacks arrive abruptly at their door, Audra’s parents insist that she flee, taking with her an important package and instructions for where to deliver it. But escape means abandoning her parents to a terrible fate.
