What's the story?

Picking up where the first volume left off, THE COBALT PRINCE finds Oona, Jax Amboy, and An Tzu ready to resume their quest to ignite the beacons that will save the 5 Worlds from extinction. Oona wants to control and refine her sand powers and find the sister who seemingly deserted her years ago. Starball star Jax Amboy seems to pay the ultimate price in a spaceship battle. Excitable An Tzu copes with his mysterious illness that causes him to literally fade away. Awaiting them is a powerful and crafty villain, the Mimic, who is able to possess the unsuspecting Cobalt Prince and thereby threaten the entire galaxy.

Is it any good?

Quest sagas require an occasional injection of new characters, settings, and dangers to keep the narrative moving, and this colorful and engrossing graphic novel supplies an abundance of novelty. The Cobalt Prince plunges Oona and her friends into mortal danger and keeps the level of suspense high throughout this volume. This series' two writers and three illustrators manage to keep all narrative elements working in harmony, although sometimes the meaning of the action seems a little obscure, especially during fight scenes. Fans of Naruto and Avatar: The Last Airbender will likely find The Cobalt Prince to their liking, but so will readers who simply enjoy a well-told tale of intergalactic magic and intrigue.
