The Lightningfall: The Relic Cycle Book 2

An ancient darkness reawakens. An empire casts its shadow over the East. And together they seek: the Lightningfall. Bowen Cord has embraced his gift. He uses his ice-summoning in service of others, while relishing the quiet comfort of raising his family. There is no denying the call to a quest, however, when a mysterious woman arrives at the Aevorn village bearing a stone with the rumored ability to reach the dead.
Bowen will have to assemble a disparate crew aboard his new cloudship, traverse the isle-filled skies for hostile lands, and determine who this woman really is-and what she wants. If not, he'll be unable to stop an empire from burying the world under a reign of ice.
