The Drache Girl (The Sorceress and the Dragon, #3)

More than three years have passed since the colonists arrived in Birmisia, and Port Dechantagne is a thriving colony, with the railway line almost complete. Twelve year old sorceress's apprentice Senta Bly, Police Constable Saba Colbshallow, and former maid Yuah Dechantagne must deal with wizards, prejudice, steam carriages, boys riding dinosaurs, and the mysterious activities of the lizardmen.
