Ominous Odyssey: Overworld Chronicles Book Thirteen

The mysterious new leader of the Brightlings is after a secret weapon. The catch? It's hidden somewhere in Voltis, a forbidden place where violent elemental forces will slap you around like a red-headed stepchild. Naturally, Justin can't let that happen and convinces Elyssa, Shelton, and Adam to tag along, because who doesn't want to ride a flying ship into hurricane-force winds while lightning tries to rip you a new one?
