My son's been on a real reading kick! I almost can't keep up with him.
We picked up these two sequels to The Lost Property Office, one of the first books I ever reviewed on this site, just the other day. The pace for Jack Buckles and Gwen, his quartermaster, has slowed down a bit -- while Lost Property takes places over the course of a day, these stories both take place over months.
The Fourth Ruby reveals what the Zed really is, and why Jack must stop using it, while The Clockwork Dragon reveals who was behind the plot to steal his father's consciousness.
Along the way, Jack discovers he's a mix of Drago and Tracker, and learns to wield his Drago powers, just like he's mastered his Tracker senses, and free his father from prison. We meet some wonderful, real dragons (not clockwork ones) in the final book, as well!
Fun, quick reads!
