Carmer and Grit, Book Two: The Crooked Castle

What dark magic powers Rinka Tinka’s flying circus?
 
After saving the faeries of Skemantis, magician’s apprentice Felix Carmer III and faerie princess Grit are eager to leave the big city behind and see more of the world. Their travels soon bring them to the ticket counter of the mysterious Rinka Tinka’s Roving Wonder Show. The flying circus delights and amazes the crowds, but Carmer and Grit quickly discover that there’s more to the show’s magic than meets the eye—and a string of local airship accidents might be the key to unlocking its dangerous secrets.
