THIS SERIES MUST BE READ IN ORDER.

Picking up where The Rogue Knight left off, in Crystal Keepers Cole, Dalton, Mira, Jace, & Joe are headed to Zeropolis, the most technologically advanced of the five kingdoms. They're searching for Constance, Mira's sister and being helped by the Unseen. The problem is, the Unseen are under heavier attack than ever before and the High King is desperate to get his daughters back. Bringing in new allies and new villains, this is a great continuation of the Five Kingdoms series and I highly recommend it!
