Sugar Rain book by Paul Park

The second book in the Starbridge Chronicles, Sugar Rain relates the stories of Thanakar and Charity Starbridge during the revolution that ended the first book in the series, Soldiers of Paradise. The generations-long winter has drawn to a close, and with it the power of the tyrannical Starbridge theocracy that maintained order during the years of hunger. But a cruelly pragmatic priest has set the stage for a new faith, and even those who defy him seem fated to play out roles that will inevitably bring it to pass. As Thanakar struggles in exile to find safe harbor for his adopted family, Charity Starbridge undertakes a mythic journey, passing through various underworlds to join him. Sugar Rain was a finalist for the Locus Reader Poll Award.
