Mysteries of Cove: Gears of Revolution

Mysteries of Cove: Gears of Revolution by J. Scott Savage is an exciting book in the Mysteries of Cove series. Treton and Kallista are looking for Kallista's father, Leo Babbage, following the events of the first book, in which they fought a dragon and saved the city of Cove (originally named Discovery). Clues they find lead them to the city of Seattle, where two factions, the Order of the Beast and the Whipjacks are in a power struggle. Caught in the middle, Trenton and Kallista aren't sure who their allies are, or who their enemies are. Will they find out what happened to Leo Babbage, and why he doesn't seem to be in Seattle as they had expected? Or will their enemies get them first?
